Well, in that case, if employers force you to install something then just tell them give you a work phone. Or talk to them, you are adults.
And if that doesn't work, well, tough luck. This sounds like trying to solve a malfunctioning workplace problem by making everyone else suffer - it isn't my or Apple's or anyone else's problem that your boss forces you to install shady apps.
And besides, what different organizations exploring what different tradeoffs? Right now the only practical options are Apple and Android, there aren't really that many options as to have a healthy environment and Google isn't immune to making decisions that can have an overall negative impact to the control that people have over the stuff they buy (see their Stadia console as an example and how it completely and absolutely removes any notion of control from people buying games - not even consoles, let alone PCs, feature such loss of control).
I know people who break from what you call the practical options in both directions -- some who reject smartphones altogether and live their lives without them, doing all their digital work on computers that they have full control over -- and some who use only the stock apps on their phone and wish that app stores were not a thing. They want an entirely managed experience.
Neal Stephenson's essay In the Beginning was the Command Line gets at some of this nicely. Some people are, as he says, Eloi and some Morlocks. That's OK.
