i think there are quite the range of users, and that neither of us should assume our personal experiences are "the norm." That said, why do you think there's been so much discussion about this? There's obviously a good amount of people concerned, seemingly for good reason.

I've not done any significant comparisons between the two app sources, but in what little experience I do have seeing apps in both locations I'm going to guess about a third of those from smaller developers (i.e. not the Mozillas of the world) had ads in the Play Store incarnations. That's a completely unscientific personal guess, however.

Not that it's relevant, anyway - the point is having options taken away without legitimate reason for doing so. Google's own history with malware regularly being found on the Play Store proves that their "justification" is control-freak bullshit. If this is allowed, who knows what other profit-enhancing rules Google will impose further down the road when they've eliminated most any escape routes? Open source devs may have to choose to use ads in order just to pay for the privilege of being installable without having to dig too deeply into their own pockets.
