one that i noticed missing: Novell Netware, I spent several years in de 90s developing software for it. It was the main office network server software on those days.

3.x, 4.x ran on relatively regular 32-bit PC server hardware. 2.x ran on the 80286 in protected mode, the only OS I know which did that.

Copies can be found at archive.org.

Banking apps came later, long after banks had moved most interaction online.

rm - ok for all ages.

grep - 18+, you can obviously use this to search for porn.

find - 18+, see grep.

reboot - ok for all ages.

echo - ok for all ages.

cat - 18+, prints the porn you found directly to your terminal.

sudo - 18+, obviously.

kill - ok for all ages. This is the US, right.

ps - 18+, no peeping at other processes.

I've been using https://github.com/teticio/kindle2pdf + tesseract to convert amazon books to text.

So that repo also disappeared. Neither is mentioned in https://github.com/github/dmca

You already had secure and encrypted backups on your phone, which you could copy and restore, if you remembered to copy them, and write down a very long password.

The new feature is apparently a way for signal to sell cloud services.

I do think cloud based backups are very useful for less technical people. But it does not really matter if your (properly encrypted) signal backup lives on a google drive/apple cloud, or on a cloud service managed by Signal.
