Turn off the issues tracker and the pull requests or deploy a bare git server for releasing your code. Find a small group of people you really know and trust and work with them on projects, or do it completely alone.

You don't need to allow strangers to invade your space. You don't need a performative Code of Conduct or an LLM policy. Open source doesn't need to be developed openly for it to be "open source".

Write code. Make things you like. Use any tools you want. Do code drops at 2am on Christmas day. Whatever you do, don't get tricked into running an operation that's half tech incubator and half daycare for people whose parents gave them a keyboard and no social skills.

I like this "my workshop has glass walls, but I'm wearing headphones and the doors are locked" model of open source.
