Ah yes, Secure Boot, which commentators here said was the beginning of the end, and that soon no modern computer would be able to run anything that wasn't Windows.
Except of course that never turned out to be the case, and it's now used by plenty of Linux distros.
Of course there is one company with a proprietary OS, that uses similar technologies to make sure they always get paid, but I don't see anyone here complaining about Apple.
