Open source drives that ecosystem & the private sector follows suit as the developers try new tools & suggest platforms from their open source experience. There are a lot of companies on MS GitHub Enterprise as well as opening some of there source in the form of libraries & they all choose Microsoft for marketing reasons over technical ones (Git is just Git after all).

You are acting like I’m saying “leave Git now or else”. I suggest it could be an option, if IMO a faster option, to get out Microsoft’s of monopoly. It’s easier to pitch as better tool with better features that solve problems than argue “well, ethically, you just self-host or move to Codeberg since user freedom matters”. That philosophical argument is harder to preach than Fossil ports the whole forge + tooling ecosystem with your project or Darcs/Pijul solve the merge conflict order of patches not commuting or Mercurial offers a more user-friend CLI.
