lots of companies send nastygrams like this even if they have no intention of following through with legal action. it costs them nothing (except reputation on HN) and there's a good chance the recipient will get scared and give in without a fight. there are important issues on the line here and it makes me sad that so many people feel like they need to walk away because of the possible legal expenses. i know it's easy for me to say this as i've never been sued myself, but for once, just once, i'd like to see someone fight back against something that is so clearly wrong.
