I’m highly concerned about this, not only due to lack of control of software I can choose to install, but also what happens once a developer is blacklisted? I haven’t seen anyone really address this.

What guidelines will Google use to determine that an app is “safe”? Will Google begin blacklisting developers who modify apps? What about developers who make apps that aren’t controversial themselves, but linked to controversial technologies or can be used for controversial means? (Torrent clients, etc.) Google to my knowledge has not provided a list of criteria they will use.

Even if Google claims pure motivations now, I think the amount of control this policy carries will be far too tempting for Google to refuse to utilize in full for any cause.
