Earlier quoted context omitted.
Mate, the general population increasingly don’t even use desktops or laptops for personal usage anymore let alone a desktop OS specific IM client from the early 2000s.
I would suggest they never knew how to use computers. Computers are general purpose devices, which is lost on the general population who only ever need to check emails and post on social media. Smart phones fit this perfectly. Let's leave the general computing devices for people who actually need that power, just like the early days.
With that attitude, eventually the impact of economies of scale will end up denying us the ability to afford those devices or to use them how we see fit.
