I'm pretty sure what you say is true, but I think it only runs in one direction: Android users who are ignorant of iOS.
However, as with computers (or really anything), there exists a sizeable group which don't use their devices well and instead have a superficial grasp of their platform, for these people switching is relatively straightforward since they rely very little on the interconnecting magic that makes the various apps and services work well together and instead mostly use the basic functionality of each app, which is relatively identical.
I've had a work provided phone and a personal phone for a long time and so most of the people I know.
Sometimes I've had a work iPhone and a personal Android, and now a work Android and a personal older iPhone.
I'd be worried about mixing up business and personal chats and photo galleries. Like if I need to take a picture with my work phone it's usually of something work related.
Or forwarding the wrong meme on a business chat, or attaching the wrong file in a family/friend message could land me in trouble.
How does it work in NDA'd work environments? Like when company's information can't leave company's devices? Is BYOD accepted in those cases? Like with MDM managed phone or workspace separation?
My wife has an iPhone so I'm fairly in the loop on the pros/cons.
I also have some Android tablets laying around and know how poor they perform.
I wonder how much the pandemic has influenced these published numbers. I don't think they can differentiate someone download app from an iPhone vs iPad? All the remote learning has had students get tablets and I personally woulda have picked up an iPad...they do have the iPad pricing and features tailored with schools in mind.
