Android does the bare minimum to be called source available which isnt the same as open source and also its only the core of android that is. Its literally like taking linux, slapping on a bunch of propeitery stuff onto it and then telling people that you cant contribute to it and youre only gonna use an old, highly modified version of linux actually. Also the whole application ecosystem that you have on it needs your stupid spyware to run properly. As for linux i dont think desktop linux is buggy. Its way more usable than windows for example which literally falls to pieces if you look wrong at it. I have 3 old classmates who switched because windows just kept breaking. Your problems with audio means you probably used a non standard setup which i admit can cause breakages theres no doubt in that. And finally chrome having a memory leak; how is that related to linux?
“Okay so you want “actual linux and open source” AND it also needs to work on more than 1% of the phones?” Is this ironic or did you actually just tell me an argument that ive first seen in a meme? Why cant you have a modern phone that also has linux - because of the stupid corporations. Also same with sd cards. If you want a modern, high end phone with an sd card it just doesnt exist. You shouldnt have to compromise but capitalism forces you because at this point there are like 5 companies that make phones and all of them benefit from you suffering. If qualcomm offered proper support, phones could have linux support but they dont.
