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?
