Well come on. GP really means category cable (twisted pair copper) is not happy at 10Gb distribution lengths (so-called horizontal cabling, although in a home it may span multiple floors without IDFs). That's kind of obvious context.

DACs are not category cable; they are twinax, short, and bulky.

pretty bad advice, if taken only as written, without adding more flavor on top.

the major email providers will penalize you if you generate too many undeliverable emails. thus, if you just send a verification email without any pre-validation, it's pretty easy to get into a DoS situation where current/valid users don't get important email sent to them, or that email is significantly delayed, plus incur huge operating cost to resolve the problem.

some form of rate limiting is needed, plus IMHO it's better to use a verifier service or your own heuristic or ML model to test for email validity including valid but fake/spammy/disposable addresses.

sorry, but we are way past the point of being able to have nice things, esp. when we're talking about email.

the "lies" part of the content is great. people do assume all those wrong things. however the TLDR is just wrong, and potentially harmful.

As is noted in the conclusion.

Not to take away from the actually great reporting here, but what they mean is, This approach allows them to milk it for as many clicks as possible.

A short half-life means you are going to quickly dispose of what you have now, anyway. In fact most current datacenters can't even handle Vera Rubin, so I don't think there's short term risk here.

  BOOBS

Assuming you don't have ECH, you leak the question (in practical terms) to your ISP, and you leak your question to the DNS provider. With ODoH you plug the latter leak. Plugging that first leak is then still a problem (solved separately) but it's orthogonal to the second.

Even with ECH, where you plug the TLS leak, you have many more holes to plug. IP address might not be shared or might be shared across too few properties, and then traffic profile after the initial connect (to retrieve all the sub-resources) can identify destinations.
