I have to say that I think this is really quite outrageous. I have never heard of any software developer refusing to update a legally purchased product based on the distribution channel.

Obviously Captain Sim agreed to have Just Flight publish its software some time ago. Whether they had a falling out is irrelevant, as they still have a duty to support the end user /purchaser of their product regardless of the distribution channel. They undoubtedly still receive royalties (or did receive royalties) for the purchase of this product, and to leave the user "hanging" without an update is extremely unprofessional. All this baloney about "supporting the developer" is hogwash - Captain Sim made a knowing and intelligent decision to publish via Just Flight, probably to get its product out to users who would otherwise not have heard of CS, myself included.

I was thinking of buying the 707 and 727 from Captain Sim, but with this kind of "customer service" I will stay far away. Other developers for FSX (without naming names) do not engage in this sort of unprofessional behavior which serves only to punish the end user. If CS has a problem with Just Flight, that is between CS and Just Flight. The end user should not be punished for this dispute, and CS should continue to support its product no matter what the distribution channel. If CS wants to stop publishing any of its future products through Just Flight, that's entirely CS's choice - but leaving the end user hanging is not only legally questionable, it's bad business. It would cost CS nothing to make their users happy (there is no variable cost associated with making the patch available to another company users, since it's not physical media) and instead they will lose business, at least certainly mine.
