The issue isn't Linux. A large majority of phones use Linux, as do many other consumer devices. Saying "Linux isn't for consumers" is extremely daft.

Ubuntu's phone efforts didn't fail because it ran Linux, it failed because almost all phone brands do unless they have Chinese backing.

Microsoft pumped billions into smartphones and failed. Was it because of Linux? No. Windows phone didn't run Linux. So I guess by the above logic, Windows isn't suitable for consumers?

Shit, HTC and LG are big names that died in the phone space despite not having the hard job of creating their own ecosystem. Samsung has walked back on Tizen and a bunch of other in-house stuff and started shifting back to Google services. Sony is only surviving by abandoning the mass market.
