None of the solutions mentioned are decentralized. Git is decentralized but those services are not, even if self hosted. There are very early projects like codeonchain.network/ and others starting out that are.
Different instances of X can replicate between each other, so you're not siloing your development, and by decentralisation I was referring more to the fact that not all open source development has to happen on a single platform.
It's OK if some projects are on GitLab, some on Gitea, and others on Sourcehut.
True decentralisation can be a worthwhile goal down the road, but right now we can solve the problem using the tools we already have.
Then we agree 😄
We're a place where coders share, stay up-to-date and grow their careers.
We strive for transparency and don't collect excess data.
