> Edit: I wanted to add I think you might be making a mistake backing down at this point. It seems that all of the problems you mention in this post relate to some small (yet vocal) percentage of your existing users being upset with the recent changes. That's a temporary problem, and probably not that big of a deal at this point since you've already absorbed the majority of the backlash you're going to get. If you think the changes you made in your latest version are the right direction for your product in the long run, then I'd stay the course.

I completely disagree with this. It might work as a business decision but it could cause problems in the future, especially if these early paying customers are vocal or previously bought your other apps. I think if a more popular/downloaded app did this (thrusting ads on paying customers) the backlash would be huge and it would severely damage the companies reputation. Just because you are a smaller business less likely to get press coverage for a bad decision doesn't give you a free pass to make it anyway.
