fajreIs there something like GitHub, but without big tech involvement, no data collection, no ads, open source, and preferably decentralized (maybe Fediverse or even P2P)?
No, because the people hiring and the people working with you will be using GitHub.
I’m seeing a growing trend where a dev’s core repo moves to a new platform, but leaves a mirror on github with a link to the main repo. I love this solution.
