This amounts to less of a privacy invasion than performed by Facebook or Google, to my mind. In addition, anyone that is under the impression their activities online are currently anonymous is mistaken. It's straightforward for rights holders to track bittorrent users to an IP, which they can then use to identify the individual.

Most of my internet traffic doesn't flow through Google's or Facebook's infrastructure (at least not to my knowledge). All of it goes through my ISP's.

On the other hand, it's not so straightforward for MPAA to identify IPs of people downloading/streaming videos directly. ISPs can, of course. Also, without the cooperation of ISPs or a shady court system (which assumes that IP in a bittorrent swarm is enough of a proof that a crime happened), it's also not very simple to identify individuals from just an IP.
