said by skeechan:
Companies are free to pick and choose who they sue so ultimately their own rampant piracy is largely irrelevant unless some local AG goes after them for something which is unlikely given their connections.
What it does do is invalidate their claims of piracy being a "problem" given they don't bother to clean up their own messes.
Very true. I would go so far as to say that it could cost them court cases. If the claimed 'loss' numbers are brought into question and shown to be deliberately inflated (by including industry piracy that they won't pursue) a judge could dismiss the whole case. It would be very interesting if a defendant subpoenaed the entire list given by an ISP and brought to light the people who were let slide.
Another legal point is related to 'implied license'... if (for instance) Arista allows RCA to share a song that Arista owns (by not pursuing them) how can they then argue that someone else downloading that song from RCA is 'stealing'?
