I haven't been around on this forum as long as the old timers, but my impression is that the reason why Aero is such a centerpiece here has a lot to do with the fact that they offer the widest range of utility and military jackets in the most combinations of leather/lining/options, so naturally they'd bring in a lot of discussion. Going back to the old threads, it was really mostly mil spec jackets from different makers and Aero for the civilian sector. The "jacket explosion" has taken place in the past few years, where more manufacturers are being brought to the frontline. But before that, it was mostly Aero. So Aero has kind of a heavy foot in the forum, because it's been talked about for a while. I don't think it has much to do with allegiances.
