The problem isn't with Amigakit making profit, it's with Amigakit making everything about Amigakit. By all accounts they're a well-run business that supports an underserved community, which is great -
however, that does not give them license to ignore basic forum etiquette (and doing so is bad PR, which they ought to understand.) Besides, if the OP was anything like Cammy's
identically-titled thread over on Amibay, it didn't even mention
anything about an app store, just discussed the recent increase in commercial publication of retro-homebrew titles and mused on possibilities to promote this kind of thing in the Amiga community. So it's not hard to see that as an obvious threadjack.
