Don't they still charge a $100+ license for Windows? I have Windows 10 for games, but I haven't booted into it in months since Steam has been fantastic on Linux (relative to it's past, it has some ways to go).
I'll be the classic Linux desktop optimist: the improvements over the last four years along have been fantastic and I really hope for a future when it can meet everyone's needs.
My OS shouldn't advertise to me. It shouldn't sell my data, or shouldn't do anything like that. It especially shouldn't harass me to log into the owning company's account. I shouldn't need any internet account to just use the OS (missing features relates the said account is obviously reasonable).
