Take any group of a hundred tech people (devs, analysts, architects, etc.), and 95 of them will do everything with their stock Android or IOS smartphone. Maybe 3 will consciously limit their use of that device, and the remaining 2 reluctantly use something sane like GrapheneOS. Those two might pipe up and take a stand for people without smartphones (which includes a very varied swath of people, from Luddites to people with disabilities), but they'll get drowned out by sighs, sheepish looks, and the chorus of 'let's just start with those two smartphone OSes, and if after a year or two people still really need something else, a new project can be started to address that'.
It's not an insane question, it just doesn't get asked.
