This is exactly what I heard. Windows 8 compatibility required there be
Secure Boot, and it be disableable. Windows 10 compatibility dropped
the requirement that it be disableable.

This is the precise problem. If I were happy with Ubuntu, Redhat and
Debian, this would be a non-problem. But as we've all seen in the past
18 months, big distros can go very, very wrong, and in the absence of
small distros, this can create a world of hurt for people who want to
rule their machines rather than the other way around. Mandatory Secure
Boot pretty much forces you into Windows or a big Linux. This is why,
before purchasing a machine, the #1 most vital question is: Can I turn
off secure boot? If no, the machine's useless.

I may start buying used machines to avoid all this stuff.

Why should they? They're Windows-Weenies. It's not a problem for them.
It's just the tiniest bolt in a huge machine.

Yeah, I hadn't thought of that.
