I am sure someone at ffg looks at the website to see how people are responding to their products, but will they act on anything? I don know. There is a faq for other coop games, so I am sure this will get one too (aside from the one included with the app?
FFG staff certainly do read the forums for their games, and in my experience they're pretty good about acting on feedback received. It will be interesting to see how they handle these sorts of clarifications in XCOM, considering the rules are all in the app.
They could just change the rules as written in the app to clarify or correct things, but then some people would be playing by outdated rules without realizing things had changed. Possibly, they might even miss the update, so then their rules will be different from everyone else's, and when they go to play with someone else's copy of the game they get a rather big shock...
Perhaps maintaining a separate FAQ (either as part of the app or as a PDF) could help maintain the change log. The app can still be updated directly, but at least people could look at the FAQ to see if something changed or if they're just losing their mind when they get a rule wrong. =P
