Most of the world runs windows or Mac for everyday things. They’re deeply inside of ecosystems of programs that aren’t available on Linux or don’t work as well. Individuals moving to Linux won’t do anything. The only way for it to gain traction is is large companies not only declared their switch, but also request and/or develop the same proprietary bullshit like photoshop on Linux. There are some companies like Valve trying to promote Linux and FOSS but for their own profit driven agenda, bur even that’s fine because at least it’s something. I can’t see Adobe doing the same
Most users don’t care about Microsoft watching them jerk off as long as the computer works well enough to let them do it undisturbed
If I was Tim Apple, I would simply develop macOS and Linux to take away Microsoft market share then halt resources from Linux development to draw people to apple.
