The end-game for this scenario is for the whole package to provide enough polish and other features that you'd be stupid to cobble together the OSS equivalents

The end-game for this scenario is for the whole package to provide enough polish and other features that you'd be stupid to cobble together the OSS equivalents after you reached a certain level of affluence. And then it's the business' job to make sure they can profit off that audience division. Good companies understand that and don't waste their time with needless software patents. Poorly run companies insist that "it's mine, you can't have it" and wind up stirring up trouble from amongst their user base. Of course, it would seem iA is in the later category. Hopefully they've done some market analysis that they still have a critical audience mass who are either ignorant/apathetic to such tactics and buy it anyway.
