What in the world are you talking about? The point is trying to fix node policy filters, fix bugs introduced with Segwit the Core devs refuse to fix, and limit some areas of consensus that have been big areas of spam abuse. Also, limiting OP_Return down to prevent Bitcoin becoming a file storage system with potential dangerous outcomes. You gotta be careful. The Core-advocates are making up all kinds of stuff. I'm not aware of any lawsuits (fill me in if you are). I think the initial release of BIP444 had a conflict with some old, rare method of multi-sig, but that has been fixed as far as I know.
