I fault them for their actions because I think what they're doing negatively affects a large number of people. It being legal and them being able to make money because of what they're doing doesn't make it okay.

To be clear: I will say the same thing about any company using using frivolous patents to suppress competition. It is a flawed system, and the people in the best position to oppose the system are the people in charge of large tech companies. Apple is not doing the best thing possible within a flawed system, and they are not trying to change the state of affairs. They are using their patent portfolio aggressively to try to suppress competition, and I think that's a problem.
