You do realise that this is effectively saying to people "what's wrong with you, just spend a few thousand £/$/€ and stop wasting time?"
Not everyone has £1000-£2000 lying around doing nothing. However, a lot of geeks have old PC hardware lying around doing nothing. One of the details I liked about The Big Bang Theory was the multiple half-cannibalised PC carcasses in the background of every shot.
Firstly donate unused PC's to a worthy cause - there are several folks in need of them than hoarding it - some people want things to work out of the box and OS upgrades to be seamless and don't want to tinker.
Hard disagree with toys poor analogy. I don't have any stats but I'm sure a huge percentage of Twitter users are not using the latest version. I'm just choosing to to run a particular version. Anybody on iOS 14 and earlier will also be running this version.
