I understand your points. If you are asking how to sell it, is not poor
audio support on Linux good argument compared to Windows and Apple

Because as I wrote, really it is better to not use Linux/Debian for
bluetooth audio and rather switch to Windows or Apple system.

No, upstream is really not interested in it. I thought that something is
happening but I was wrong.

I'm stopping communication with upstream. It is just takes time and has
no result. After 2 years basically nothing happened. Seems they do not
want to touch anything bluetooth related and they like current state.
Looks like that they also lost other developers as I do not see any
activity on bluetooth part.

So, what about contacting other Linux distributions and maintaining
patches collectively? I'm sure that users of other Linux distributions
are interested in improved bluetooth audio support based on feedbacks
which I got in private emails.

Let me know what do you think.
