Google needs to do something. They absolutely do not need to mimic Apple's policies or impose any radical new limitations but the current situation is starting to spiral out of control. Once this starts hitting 'normal people' it could have massive repercussions. They need to stop this before the average person fears installing software onto their device or the entire third party ecosystem is going to be stunted. When you think about the depth of personal information, location awareness, microphone, camera, etc the ramifications of this are huge. The first virus that leaks SMS messages, owns Facebook accounts, or turns on cameras to spy on people could basically end Android as a viable consumer product. Of course we've seen this all before on PCs but I think the stakes are higher these days especially with devices that are so personal and highly connected.
