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.
