Do you really want Linux phones
Probably an unpopular opinion, but I don't think most people who buy a Linux phone actually want a Linux phone. They want an open-source phone. The Linux philosophy isn't important to them, they essentially want open-source iOS (with all of the polish and out-of-the-box doodads). They want the ability to make modifications, and they want the freedom and transparency that open-source gives them, but they don't necessarily want to open a PR against the camera app if they want it to more closely match the polish of iOS.
