At least one MSFS designer reads these lists and has been in touch with me about the 310 model (which I designed). I don't consider that a problem -- the person I corresponded with, at least, wanted to share ideas and feed fixes back into our data. In any case, it's worth remembering that we take many of our stability numbers from other people's work (like Roskam's).
I wouldn't have a problem with that either if they respect the GPL, which in most cases they don't. Further more it take a considerable amount of time gathering all the data, and just taking the data for your own good is, so to say, not nice.
On the other hand, if they let us use their 3d models, I wouldn't think of it as a problem either ...
I think that an application-independent public database of stability coefficients would be a worthwhile project in itself. It would be useful for FlightGear, XPlane, and MSFS, and we'd end up with a much bigger pool of contributors.
Hmm. Maybe I'll start on that.
I expect it to be harder then you might think in advance.
I know there have been a few weak attempts in doing so, but none have ever gone any further.
