If Linus would be a non-techie, he would have tried to install it with a graphical AppStore, it wouldn’t have worked and he’d either given up or found the flatpak version of Steam, which would have worked. Not restricting power users is a good aspect. If I play around with Windows registry to force the removal of edge, Linus would blame me, not Windows. You have to differentiate between things normal users tried and things Linus attempted because he has some technical knowledge.
Some random user saying anything doesn’t make anything true, you don’t believe flat-earthers on the internet, either.
Let’s hope they’ll use GNU Taler for this. I only heard it being considered in Switzerland.
