It actually seems more like a windows 10 compatibility dilemma for developers. You can support older systems but it would require some effort. The problem is not the absence of some specific certificates, but the absence of newer ciphers altogether.
This does give security but also removes backwards compatibility with some clients that might be important for some websites.
Steam getting better isn’t linked to anyone becoming a billionaire. That sentiment sounds like people can’t stop looking for things to blame Valve for.
Is it too difficult to accept that every single company failed in competing with Steam? I’d say they didn’t even try their best (especially Epic). Must’ve assumed that just serving a website with a web app is all they needed to get as rich as Gabe.
