>not getting out of bed for less than XXXXX

I just made up the figure. Perhaps 10 billion dollars is more enticing. Perhaps you have to purchase the company outright and then dictate they add support. My point is that it's not impossible to get the apps people need to work on an alternate Android OS. It is a matter of funding conpatibility. You can find a niche audience of people to start out with to make a competitive OS for them. And then overtime expand that audience more and more.

>Aren't you asking them to maintain compatibility

Typically the complaints about banks is that they use the Play Integrity library which doesn't trust other operating systems. So the ask is to support the Android API for integrity and to trust the key of the OS provider. This would be done via a new library to make integration easier and more foolproof.

> It is a matter of funding conpatibility.

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)

> the Android API

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.
