> If app stores allowed paid version upgrades this trend might not have happened. I prefer the subscription model myself. If you don't renew the subscription you get ads, or whatever happens now. Updates fix security issues, and enable Android's API to move forward. Not having them because you didn't pay would create a large base of software obsolete UI's, buggy software with security issues which will create huge problems down the road. I'm not surprised Google doesn't like the idea.
