regarding Limewire & Frostwire ...

"The project was started in September 2005 by members of the LimeWire open-source community, after LimeWire's distributor considered placing "blocking" code which it was developing in response to RIAA pressure and the threat of legal action in light of the U.S. Supreme Court's decision in MGM Studios, Inc. v. Grokster, Ltd. When eventually activated, the code could block its users from sharing licensed files. FrostWire was first released in October 2005.

FrostWire is based outside the United States, possibly to avoid legal liability. The FrostWire team has stated that they will never use "blocking" code similar to that which is used in LimeWire."

Those 2 paragraphs are quoted from Wikipedia, and I have checked the accuracy.No evil or malicious companies are taking over P2P, so all can relax.
