I think Sean's Press release may be just a victim of bad phrazing.
The first problem I see is actually a common advertisment mistake. As opposed to pointing out the strengths of his product, he's pointing out weaknesses in others. This tends to make people warry of your product no matter how good it is.
What I think he is trying to convey is that his company philosophy is to create products that will not overpower characters and unbalance the game. Furthermore, it's goal is to show "why" certain things are unbalanced in the context of the game. IE rather then just say the following feats are unbalanced, his aim is to give people a basis on which to "ruleswise" come to that conclusion. I'm sure we've all encountered rules that we didn't think would be a problem only to realize several games later how MUCH of a problem it actually is.
This is a bit tricky though. If he sticks to why in the context of a "core" game certain rules are overpowered, I think it will be ok. It's important to remember though, that one group's out of balance might be just right for another and that the various companies exist to fullfill these varying wants and needs. Sean, however, is a very opinionated guy, and my fear is that he will come across with the attitude of "this is the only way it can and should be." in his products.
p.s. Psion I completely agree with your signiature statement. and btw, congrats on that whole magazine article you're bio is in.
