In EULA-like situations where you "can't" negotiate the contract, it's not clear to me whether reading it is a good move, game-theoretically.
What I've heard from a lot of WA devs is "yeah, if it looks like it's going to be a problem, I'll just move to California." It's nice that option exists, but it's kind of silly that "defensive relocation" is something people even have to consider.
I don't think this works. You'll still get sued in Washington.
