DHH having to deal with gatekeeping attitudes like this and particular political prerequisites is the reason he created these “dotfiles” in the first place. I actually know several people who are not very technical and never Linux users who installed and switched to it as their main operating system. So I think what’s actually going on here is a lot of people are butt hurt that this is getting attention and having success when nobody else has before has.
You don't think it is unfair that projects that have basically been xkcd 2347's "a project some random person in Nebraska" don't get a penny, while DHH who gets millions for a bunch of dotfiles, is unfair? I don't contest that his dotfiles may be useful to some people, only that all these companies didn't care to give significant money to open source projects that they all rely on to make their billions. But when one of the 1%ers shows up with his hobby project, they all stand in line to donate millions.
To give an example: Digital Ocean is giving Omarchy $3M, while they cancelled their $50 per month GNOME/Flathub VM sponsorship a month before [1].
