The United States' Federal Trade Commission[^1] sued Amazon in 2023 with this pretext.<p>In Germany, the Federal Cartel Office fined Amazon[^2] 59 million euro (68.7 millions US dollars) because of "abuse of market power" with anti-competitive practices.<p>The European Commission[^3] also opened an investigation regarding Amazon's practices regarding Prime and the "Buy Box" (I had to look this up, apparently it means being picked as the default seller for a product where multiple sellers are offering it), since you need to pay extra for FBA to have your products marked as Prime (appearing before on the search results, and being the "buy box") and Amazon itself competes with you sometimes, being both a marketplace and a seller.<p>[1]: <a href="https://www.ftc.gov/news-events/news/press-releases/2023/09/ftc-sues-amazon-illegally-maintaining-monopoly-power" rel="nofollow">https://www.ftc.gov/news-events/news/press-releases/2023/09/...</a>

Whether that is the LKML+git.kernel.org, gitlab.gnome.org, salsa.debian.org or Sourcehut, or GitHub. At least Sourcehut isn't completely proprietary and shoving AI down your throat at every possible chance. The same can be said for Codeberg and almost any GitLab CE, Gitea or Forgejo instance</p>

<p>> Do you also dislike the concept of requiring to be a certain age to say enter a strip club or a sex club?<p>You can't compare someone checking your document before entering a strip club (or even a pub, or asking for alcoholic drinks) vs a computer system getting <i>and logging</i> an attestation and verifying it against a government database (or third party) where the Govt knows who the credential belongs to, and who's checking it. Along with my government "compelling me" to run software (even if it's open source itself) that requires me to have a binding contract with a foreign third-party company known for privacy violations, and running their proprietary software stack on my device for said government software to work, so I can participate in most parts of the digital society.<p>Of course the existing "identity verification" done  by scanning yourself and your ID document (passport, national ID or driving licence) is not acceptable, unless counted exceptions where said documentation is needed (banking and others, because of KYC/AML)</p>

<p>The problem is "markets can stay irrational longer than you can stay solvent". It doesn't matter when the bubble pops if the governments (especially the US') bail those companies out.<p>The damage is already being done, whether you are a 401k/IRA holder with a position on the S&P 500 way too overweighted by the Mag7&co and their circular dealings, or just needing to buy computer parts way over their market value because some companies are over-leveraging to outcompete you for that hardware (or electricity), or even at a smaller scale by increasing software costs because everything is "AI-powered" now and of course you wouldn't want only "deterministic" software that just works and doesn't have a slop machine integrated.</p>

<p>It's not about it being hard, it's about delegating. Many companies are a bit less sensitive to pricing and would rather pay monthly for someone else to keep their database up, rather than spending engineering hours on setting up a database, tuning it, updating it, checking its backups, monitoring it and making it scale if needed.<p>Sure, any regular SME can just install Postgres or MySQL without even setting much up except with `mysql_secure_install`, a user with a password and an 'app' database. But you may end up with 10-20 database installs you need to back up, patch and so on every once in a while. And companies value that.</p>

<p>End-to-end usually means only the data's owner (aka the customer) holds the keys needed. The term most used across password managers and similar tools is "zero knowledge encryption", where only you know the password to a vault, needed to decrypt it.<p>There's a "data encryption key", encrypted with a hash derived of your username+master password, and that data encryption key is used locally to decrypt the items of your vault. Even if everything is stored remotely, unless the provider got your raw master password (usually, a hash of that is used as the "password" for authentication), your information is totally safe.<p>A whole other topic is communications, but we're talking decryption keys here</p>

<p>At this point, end-to-end encryption is a solved problems when password managers exist. Not doing it means either Microsoft doesn't care enough, or is actually interested on keeping it this way</p>

<p>Every government in Spain for the last decade or more has been cutting corners in maintaining the rail networks: high speed (where this accident happened), the  conventional network and commuter rail. You failed to mention the fact our budget has been extended since 2023, that the actual track where this happened was given maintenance under a year ago (per the minister, [^1]) and the train that first derailed (Iryo's ETR1000) was last checked 4 days ago.<p>Regarding the former Minister (Ábalos), he's awaiting trial and not yet convicted (even though, IMHO he is probably guilty), and he hasn't been in the ministry since 2021[^2] so it makes no sense to bring it up when he has been out for nearly 4.5 years now.<p>[^1]: <a href="https://www.lavozdegalicia.es/noticia/espana/2026/01/18/oscar-puente-sobre-accidente-adamuzdos-vagones-tren-renfe-salieron-despedidos/00031768773270864198878.htm#:~:text=En%20ese%20tramo%2C%20los%20trabajos%20concluyeron%20el%20pasado%20mes%20de%20mayo" rel="nofollow">https://www.lavozdegalicia.es/noticia/espana/2026/01/18/osca...</a>

<p>On the other hand, it may end up the other way: pressure you or bully you into quitting yourself. Here in Spain it happens sometimes: firing you is expensive and they don't want you around for whatever issue, so they'll try to find any justification to fire you, or just pressure you in some way on another to make you miserable enough to quit. No doubt that would happen in the US.</p>

<p>Yes. At least in 11 Pro installs, you can just say you'll be joining to a domain, create a local admin account and never actually join it. Then to create other users you can do it via the command line, or probably through the GUI after telling it you don't want one a couple of times</p>
