Google is doing everything they criticized Samsung of doing. Whip out your Nexus device brand new, it comes with all the Google stuff. Hangouts, Music, Newsstand, Google+, etc. Can't be uninstalled without root. How is that not basically the same as bloatware? That and to this day Play Store still refuses to work correctly. I got rid of it and thr rest of Gapps long ago. Surprisingly I've never had a reboot, crash, lag, or horrible battery since.
It won't be another operating system that upsurps Android, it will be Google policies leaving bad tastes in the user's mouths. Rooters, rom flashers, etc are a minority among the user base. Google is too big for their own good. They encourage and demand the removal of two key advantages over Apple, removable storage and replaceable batteries. They cause development of AOSP alternatives to Google apps to cease. They criticize Samsung and Amazon for offering competition to Google Play. They seem to be moving away from the Android name itself. Their ads lately refer to the entire ecosystem as Google Play.
