If anyone from Motorola reads this thread; the market is beyond ripe for a good shake up. Going full open source and pushing updates & openness, user control and freedom, you will gobble up a good chunk of market share. Make MDM easy & first class (no third parties...), and a ton of corp will roll it out too. We need you more than you think.
Even with a fully open-source OS and first-class MDM, the company would struggle to gain significant market share. The Hardware Root of Trust and the binary blobs would still be compiled by a firm that Western governments view as a fundamental supply-chain risk.
