Kind of. There is the PinePhone and Librem 5 that both run full Linux. I have a Pinephone. Unfortunately, the hardware is underpowered and the software is not ready to replace iOS or Android. The battery is also not good. The standby has improved a lot, so it can last a day of limited use, but the battery drains very quickly when the device is actively being used. It’s definitely fun to play around with, and it even has the convergence feature Microsoft tried to do with Windows Phone. The UI changes to regular desktop Linux when plugging the phone into a monitor and connecting a keyboard and mouse. But again, the hardware really limits what can be done.

In short, Linux phones are a thing, but not reliable enough to be the only phone a person has.

Good old reliable RSS. You get exactly the sources you want and without an algorithm trying to influence what you see.

Audiobookshelf works great and is very easy to setup using Docker. I get most of my audiobooks through Downpour. They have a subscription that gives credits to redeem for audiobooks similar to Audible, but they are drm-free. I download the audiobooks and move them to my NAS that has Audiobookshelf running on it. Audiobookshelf has a web client and apps for Android and iOS (TestFlight beta).

That’s one of the most significant reasons I stopped using YouTube Music.
