looser IPR rules more favorable to rank-and-file developers seems like such a basic, shared concern that it's likely to be a plank of any organized labor in software development.
For SV specifically, I have a hard time seeing this as a major issue let alone an organizing one - mostly on the basis of personal impressions but also historically - there would be no SV at all if this was some serious impediment at a time when patents mattered a lot more than current software patents do. Why do you think it's such a big deal? It does pop up a lot on forums but lots of things do and more often than not, it's people being surprised and shocked (not entirely unreasonably) at the first AoI they get when they start working around here. But in practice, these (among halfway decent actors) are almost never used in a coercive or draconian fashion.
