I would add that desktop Linux only exists today as an alternative to Windows because of those values. This history of Linux desktop environments and applications is rife with examples of popular or personally important bits of software that were forked and kept alive by the freedom granted by FLOSS licensing.
If "Linux" was a thing that MS could have bought and then destroyed or enshittified, they'd have done it twenty years ago. And make no mistake, they continue to play the long game.
Yes, we should all be good to newcomers. No, the direction of desktop Linux should not be steered by wanting more of them. It should be steered by a need to provide desktop Linux for people who enjoy using desktop Linux.
