The problem is that most normal people (HN is not normal - mostly for the better) don't even understand what sideloading is - let alone actually care.
How can we fix this?
(aside from making people care - apathy enables so many political problems in the current age, but it's such a huge problem that this definitely isn't going to be the impetus to fix it)
SteamOS isn’t too far from a mobile OS.
I would wish that mobile devices' specs and hardware drivers are all available, so that i am not dependent on the manufacturer supplying a compatible OS.
