maybe in the USA but for those of us living in that enclave known as 'the rest of the world' we've been enjoying phones without carrier bloatware and bundling for years.
I think cm is doing this correctly, more so than Ubuntu or FirefoxOS. Android has already done the heavy-lifting for an open mobile platform. It seems counter-productive to redo the work.
If Ubuntu produced a better launcher and its own appstore for android I'd love to try it out. As it is, the only way they can drum up interest in their product is to spread fud about Android.
