From what I understood, you didn’t want to open-source Summit because you don’t want to allocate your resources to managing issues and reviewing pull requests amongst other reasons (correct me if I’m wrong!). I don’t know if you can disable Issues/PRs on GitHub, but I think it would give a lot of (potential) users peace of mind if the source code could be reviewed. As far as licensing goes, you could go quite stringent with an AGPL if that is a factor, to prevent closed-source clones.

Anyways, I find it sad to see that Summit often gets bashed in Lemmy application discussions for being “yet another proprietary app, no thanks”.

That said, if setting up publishing actions or other packaging shenanigans is a hurdle, I’m sure there’s people who would love to help.
