Seriously, you can't make a list like that and forget about Sony. C'mon! Sony, the company that basically owns RIAA, fought MP3 for two decades, said trojan root kits on their CDs wasn't a problem because their customers doesn't know what a root kit is, and is the evil mastermind behind patents like
1) blu-ray player call home
2) blu-ray player check disk DRM licence
3) if DRM licence not good;
4) blu-ray player commit suicide,
5) you have to go to an authorized Sony store to have the player unlocked (and the suspicious disk released)...

If they implement that patent, buying a movie on eBay or the local corner shop, not to mention rentals, will be a gamble that may or may kill your $400 blu-ray player if there's something wrong with the DRM licence.

Sony needs to be on the list.
