I disagree with your assessment. There are plenty of competent programmers who are working on pushing forward this software, and even following from the outside I've watched massive improvements over time.
We needed (more) open hardware before the software could get properly started, and that's what Pine provided.
As someone who has used the latest iOS and Android, I can't agree. The performance of the Pinephone is indeed really terrible, but the usability in general is also awful. There are just way too many little details that are missing, most Linux apps are still not really built for touch. It will be a while before all the important apps are fully ported over to Qt Quick and libhandy/libadwaita, but maybe by then they will have made a few more revisions with a better CPU. And of course I expect desktop users to start complaining when that happens because some apps will start to get more mobile-oriented...
To be fair, they're clearly marked as "Beta" on their store.

Until there's somebody who is willing to be embarrassed by the state of this software, and able to do something about it, there is no hope here. It does not get better.
