I read this sort of advice a lot here on HN and it always puzzles me. If I were to believe HN, the only way people ever do business in the US is through their lawyers. Or, at least, the moment there's some sort of misunderstanding or screwup there's always someone on HN who says "lawyer up!" and it's usually the top comment. Somehow, apparently, trying to sort things out the oldschool "hey we're both businesspeople, let's talk" way is considered a dangerous approach, and I don't understand why.
While I agree that this is probably the best approach for dealing with a company like Facebook that's notoriously difficult to get in touch with, shouldn't it really just be a "last resort" sort of thing? Why is it always recommended to start with legal threats? Isn't that the business version of "shoot first, ask questions later"?
I ask not just to criticize. My company is slowly starting to do dealings with American companies (small amounts, nothing like the stuff in this post) and if half our business communication is going to be in legalese we have some serious preparation to do.
