Most of the core apps I use every day (Outlook, Office, web browser, Teams, Skype, Netflix, Prime Video, etc) are available 5+ platforms
That's nice for you, but not everyone is so lucky. It's definitely becoming more viable to move off Windows, but there are still many useful applications that are native to Windows and not available on most or all other platforms. Pretending that simply migrating off Windows is a practical option for everyone isn't going to solve this kind of problem.
I write this as someone whose businesses really have so far refused to adopt Windows 10, other than for specific testing purposes. But again, we recognise that we were able to make choices that newer businesses who are buying their hardware and software today don't have any more. What we do would also be impractical for larger businesses where realistically you need a consistent desktop deployment across many users, whereas just about all of us here are technically literate and have a customised system anyway so we already use a diverse range of hardware and software.
