When you pay money to Drew DeVault and his crew, their work is all open source. And, that includes work outside of Sourcehut. They are also hired guns for existing open source projects.
My issue with Sourcehut is their arbitrary exclusion of certain classes of floss software. They're of course within their right to refuse hosting any software they don't like, but their ideologically-driven stance leaves a foul taste in my mouth and sets a horrible precedent for other misguided folks to follow.
If sourcehut is ever accepted as it is now and grows to become a major hosting platform for floss software, the entire floss ecosystem will suffer as a result.
For this reason I hope they correct course or remain forever insignificant.
