Where else do you host where you can easily attract potential contributors, sponsors and recruiters? Self hosting is not a solution since everyone would have to maintain separate accounts on all those instances. The discoverability is also poor. Git's decentralization is a wasted opportunity if discoverability and participation aren't equally decentralized. On a related note, I like sourcehut's design. I am not completely familiar with it, but I don't think you need an account at all to contribute.
