I think the attitude frequently adopted by open source maintainers - comparing themselves to Spielberg - has been a major roadblock to anyone looking to contribute to open source projects for years.
Why are you looking to contribute to open source projects? If you have a fix or a new feature, you can share the diff in variety of ways. The maintainers are not obligated to review, discuss, and accept your changes.
Agree that even prior to LLMs those projects weren't terribly welcoming as per Linus' famous email comments (chalk it up to cultural communication differences :) )
