I can't really follow. You say "I think the annoying part is that it is clearly illegal under most understandings of the Fourth Amendment," but at the same time say "I also think it's a pointless exercise to understand the legality of it."

I get the feeling the question being asked a bit leading, since you've been pretty hostile to me so far. I don't have a great answer, civil engagement and supporting politicians that also think it should be illegal for private companies to create gigantic mass surveillance dragnets?
