I have some of my code BSD0 licensed (in practice public domain). One thing that I'm vary of regarding Copilot is: what would happen if my code would become a part of some proprietary code by a big multinational corporation and then they would DMCA me out? I'm a bit in the middle of a digital housekeeping and I think I will move my code somewhere else, because of it.
Your code will end up on GitHub anyway if other people find it useful, as the majority of developers don't even understand you can self host git repositories, so they only know how to do their own development by taking the code they find and putting it on GitHub first.
