If you Read The Fine Article, it says that people disable UEFI for Linux. And, like you, they point out that secure boot can be disabled instead.

I pointed out that they list zero additional reasons people give for disabling UEFI, so it is hard to evaluate how to fix the "last mile" for those cases.

Calling that FUD when it is literally in the article is unkind at best. I shouldn't have to reiterate stuff already said in the article in order to avoid hurting the feelings of Linux users who haven't.
