A individuals rights end when they impinge on the rights of others. That said among the rights granted is the right to hold property. Thus we have the crime of trespassing. Property is a domain that is deniable to others for any reason except for those that are precluded by laws established for the common good. That said Microsoft and Sony can deny access to their property to anyone who fails to meet their preconditions for entry. Further more those conditions are hardly arbitrary. In that they protect both the owners security and property, but also the safety and property of their guests.
Modified hardware can also be malicious hardware. Both Sony and Microsoft have a legal right to defend both their own property, and themselves. Further more they have a right to protect their users which are effectively guests under their own roofs. They further more function under rules of hospitality. Their guests have a reasonable expectation to be cared for in a good manner. The companies have obligations to protect them from harm so far as it is in their power to quite reasonably do so.
Microsoft and Sony have the right to protect themselves and others. Further more it is expected of them to do so. Thus they do not have to allow anyone access that they can reasonably view as a threat. Either to themselves or to others. Honestly this isn't all that complex. Frankly you should be well versed in this concept seeing as most everyone without regard to borders by the age of six should be fluent in both the concept of others and others stuff. Hell most primates are familiar with the concept. You cannot use someone elses stuff without their permission. Civilization is based upon the concept of ownership.
Now if your arguing that concepts of ownership, space, and self defense are beyond you. Then I would argue that you are being intentionally dense, and thus just trolling. Not even halfway decent trolling at that. Yeah sure whatever, but if your going to keep on this line. I think it is just a good argument for people to ignore you from now on. Sure I think the occassional troll or devils advocate is fun, but they should at least put a little effort into that.
