I don't understand how anything you're saying addresses the fact that Amazon is deliberately sabotaging their product for users of Google hardware. Years of consumer complaints haven't solved the issue. So what's the resolution? I'm not saying this is a great move by Google, but if it results in Amazon finally supporting my Prime membership to the same extent it does for Fire TV owners, then I'll take it.
None, because Google itself is engaging in anti-competitive behavior left and right. They sure as hell aren't going to lobby for the government to crack down on these practices when they are so dependent on keeping the status quo.
