GOS can just talk about the upside, their solution to this problem. That's great work. But they often choose to denigrate others, which is destructive, damages relationships (the most essential assets - especially when you have no money to offer!), and is myopic: GOS's sh-t stinks too; they f- things up too. Forgive us our trespasses as we forgive those who tresspass against us.
It seems especially dangerous being entirely dependant on Google's goodwill; Google has zero need for GOS. I'd think Motorola, who now has money and reputation depending on GOS's success, would tell GOS to zip it. If I were in that industry and looking to partner, I might love GOS's technology but their behavior would be hard to overcome. For example, I love OpenBSD, but who partners with them? And OpenBSD isn't dependant on someone else.
Just zip it, be professional, focus on what you are doing and not on others. Great job on this fix!
