I don't really understand your argument here, isn't Google's announcement also entirely one sided? I also don't see any "discussion" of disadvantages of their solution in their announcements. For example, the "over 50 times more malware" stat is stated without any source at all, same with "Most of your users’ download experience will not change at all" (inb4 I don't care about power users at all). Not to mention stats about scam-by-sideloaded app, anything that would suggest that the proposed solution is going to work.

The point of "keepandroidopen.org", in my understanding, is to be a quick PSA on why the author of the website thinks this is a problem with some call-to-action. It's not supposed to be a place for discussion, it's at best a discussion starter, one of the sides of the discussion to consider. Obviously they present their side, as Google has presented their side.

And anyway, how are users supposed to hold this "reasonable discussion" with a corporation? I know that Google had some sort a feedback form about this, and that they made some changes, but that is not a discussion. I didn't really actually see any "reasonable discussion" being held on this topic ever, anywhere, ever, nor do I really see how it would happen. I don't even really see a good reason for Google to hold such a discussion. It's a decision made by a corporation, about their product, after all.

Could you present your how you see this "reasonable discussion" being had? Where? How?
