I'm not generally into conspiracy, but as I keep trying to work out the

Might explain quite a lot, actually, (particularly at the FAQ section 
under "When did this start?") and why it feels like macOS has taken a

I still have High Sierra installed on my 2017 15-inch Mac, and will 
likely keep it that way forever... if for nothing else, but as a 
reference of what once was.

Staying away from Big Sur for as long as I can.
