While I understand why you want open source drivers, the situation hasnt improved for 10 years, and this is one of the major reasons many phones end up not getting Android updates, which makes Google/Android look bad.
* I remember having major issues with printer drivers on Linux 10 years ago. Nowadays thanks to IPP support I don't need any drivers any more. I had to help my dad with installing a windows driver while on my Linux laptop it just worked.
* My Laptop from 13 years ago didn't have free network drivers. I had to jump through hoops to install them. Now they are all free.
* AMD has started maintaining really good open source driver support for their GPUs
* Even for Android there is improvement, with e.g. free Mali drivers being built. It's slow and not enough, but improvement.

Still waiting for them to reach parity for my laptop GPU, it used to be OpenGL 4.1 with hardware video decoding, nowadays I just get OpenGL 3.3 with the open source driver, the antithesis of really good.
