Yes, it's all true but the issue is you can already do a lot of those things with a lot of cheap hardware that is is simply easier to support than old phones. And when it comes to phones being phones Android is really good and has a lot of apps. I think the problem with Linux phones getting more popular is that the overlap between desktop/server and mobile is very small. I mean I use my phone only for phone things and a lot of things I do on my phone I can do only on my phone (e.g. charging an electric car is basically impossible without a Android/iPhone). Having a phone that can do some things desktop/server can do but can't do a lot of things a phone can do is pretty much pointless at this point.
When we'll get a proper Linux phone with full Android apps support and convergence it will be really awesome but I just don't think there's enough interest to get there at this point.
Well, she didn't win enough.
