Well then ya have a chicken and egg problem, if hardware manufacturers don't care to do things 'correctly' because of lack of interest in Linux adoption, but there's no Linux adoption because of the lack of 'correctly' done hardware.

Basically Canonical was like 15 years too early on this one. They created phones capable of running Ubuntu Touch, but the price tag and lack of supported apps probably killed interest in it. With Waydroid, now, you can supplement the apps with android apps until the Linux phone app ecosystem catches up.

We need a large funded Linux project to foot the bill on making the correct hardware to get the Linux adoption, but Canonical already tried that and failed back in 2012. 15 years later, I think the world is finally ready now, for a Linux phone.
