Why do you think this? People still use open source software and most of them don't immediately turn to a LLM if things aren't working for them, or they want additional features. They have to ask.

What has changed immensely is support. Stack Overflow sites are dead. Forums still get traffic but the impetus to sign up used to be "help me!". LLMs are doing all this work now.

The drive is going remain engaging with people, getting donations, taking about stuff. But I suspect the route into these communities is going to have to evolve.
