Key clients requesting support for the alternative OS will be a way faster route IMHO. The same way nobody bribed banks to support android, they saw the market share and potential and decided by themselves it was a worth doing. Which is why it came so late.

I understand you're offering a way to get around the chicken and egg problem, I'm saying dealing with the supply part is crazy hard. Somewhat paying users to buy into your ecosystem despite the lack of support could be a better use of money (I'm thinking about Meta subsidizing Occulus until it got some traction, and I assume it's still in the red after so many years)

People loosely explain the lack of technical challenge, but from the institution's POV you're asking them to expand their trust from Google, a US company which will be solely responsible if anything critical happens...to potentially each single phone maker, whoever happens to be selling the device to your clients ?

If Google didn't exist that's what they'd do. But Play Services is a thing. The more I think about the less I see an incentive for any established player to do that move until customers are actively clamoring for it. There's just no upside otherwise.
