I think we’re talking largely at cross purposes. It might be a good idea for maintainers of open source projects to listen to all feedback. However, nothing obliges them to do so, and you’re not entitled to be angry with them if they don’t.

If someone relies on a piece of open source software on the assumption that it will be maintained in perpetua for free, then they’re simply foolish, and they have only themselves to blame for any resulting harm.

You seem to be forgetting that this applies just as much to the people who maintain open source projects. The endless negativity inevitably has an effect.
