The pedantry comes not from someone using their User Agent however they want to use it. It comes from a company trying to (with receipts and lawsuits to prove it) LITERALLY redefine the World Wide Web into their own money making machine, and punish anyone who rocks their boat. They can cry "legal argument" all they want. At the end of the day, they're trying to force pedantry on their users. The only problem is most of the public has bought it Hook, Line and Sinker.
