Their point seemed kind of valid, so here it is...
On Scirra's home page IOS & Android logos are displayed as big as the HTML 5 one giving the impression that Construct 2 game engine directly publishes to these platforms (instead of advertising AppMobi or Cocoon)
I like Construct 2, but by no means do I currently consider it a mobile platform game development system.
Heck I asked I think a month or so ago what route show I go to make a mobile game (ie Cocoon or Appmobie) and even Ashely didn't give a response, he did reply to the thread indicating to me there is no "best" or even great route to make decent AA mobile games with Construct.
The poster stated they thought that Scirra was advertising IOS & Android is because Gamemaker can natively publish to these platforms, so Scirra is trying to me a ME TOO it seems.
.... flame suit on :p
