All I'll say is that you're likely to see significant changes with Mediatek .. they wouldn't have participated in the Android One programme if it was their one and only prerogative to close and obfuscate. Hadn't heard of Meizu? Well, in China their pre-orders for the MX4 hit 7.7m before they had to shut them down and then delay the device by some weeks due to the colossal demand. It's why Canonical's deal with them is so huge, rather than being "just some Chinese OEM" as many people thought when it was announced that Meizu / BQ were the launch partners for Ubuntu Phone. They're likely to make a big splash in EU & NA next year, too.
