I think one factor to this is that PC gamers are hostile to telemetry, and couldn't give a damn if the reasoning for it is advertising, real world feedback on game design which would feedback for future patches or the next game, or a mutual benefit of "hardware like (this) generally performs like (this) at low/med/high quality preset".

Is there any data to support this? IME most PC gamers I know don't give a shit about telemetry. They are stock Windows and Android users, love Google products, etc.
They only care whatsoever when it comes to adblocking, because they don't want to watch ads.
The only thing I've seen which is close is Star Citizen's telemetry: https://robertsspaceindustries.com/en/telemetry
