Ferrox was open source, remember. I think Dragoneer knows there's more positives than negatives there.
I'm most surprised with the Weasyl dev, though, because Dragoneer has always been paranoid about that kind of stuff. This leads me to believe that Charmander is probably feeding him insider information. Who wants to bet a future announcement of new Phoenix features includes most of what Weasyl collected from their feature request thing?
Also it's really fucking funny that the Phoenix developer is another person with a Pokemon character.
