You are absolutely right here. If anything the excluding of implied warranty works better in the US than many other countries for Open Source as typically a price is required for implied warranties to exist but even there are limitations.

I also tend to agree that there is a certain level of added burden that comes with popularity that you cannot get rid of. This starts from the basic fact that I noticed a few years back of becoming a target of social engineering.

I do however think for as long as we believe Open Source is a good thing and there is limited ways for developers to receive monetary compensation for their work, we should be quite careful here. Enrolling people into things purely based on the popularity of their creation without compensation to me feels problematic.
