Pure AOSP & mini Gaps.
Truth is Google is fighting against higher adoption of AOSP. First they tried with silver and gold program but they failed along with one, now they are bribing & that will also fail. Simply AOSP can resolve a lot of fragmentation, security and other problems, it's basic & you have all the choice there is to use what ever you want. Google did turn into the wrong direction making manicure heavy not efficient apps that people actually shouldn't use as there are much better open source alternatives like for instance K9 mail vs default mail app or Google ones & Open Camera vs default or Google camera. Any how peple should definitely need to be able to make their own choices & not forced ones from any company. Some of obsesses Google is or where using: you couldn't log to play store without G+ account (obsolete now pretty much as G+ is), the secondary services are tied to Google play like play news, books & music - video so you can't uninstall some of those apps as market will force bring them back. Naturally their is more but I thing this is enough. How many times did you mention fat bottom girls (Google employees) when Google play back services quietly updated not asking you anything wile you whose on the bad cellular connection, in roming or simply doing something else?
