BitTorrent™ is suing several spyware companies over trademark infringement. They want to keep spyware/adware companies from banking on their name, which is perfectly understandable. P2P companies need to be extra-sensitive to this, considering the abomination of adware Kazaa was.
Here’s what has me paranoid, though. µTorrent and other 3rd party clients are encrypting the protocol. Bram Cohen does not think the protocol should be encrypted. Will BitTorrent™ file trademark suits against 3rd party developers that implement features that BitTorrent™ doesn’t like?
