> but they can't use them on an iPhone

This is the World they themselves created by consistently supporting coeporate-controlled computing, in which they are just a guest on their own devices, so my sympathy is limited.

There have been plenty of warnings over the past 20 years that this scenario is unfolding, but people wilfully ignored that because "it just works" and "but what about my banking apps?!".

Maybe it's not appropriate to go Full Stallman on your colleagues, but have you challenged them to change their purchasing choices for the future?

It hasn't been unfolding over the last twenty years, it was like that from day one for iPhone development.
