I don't know, here in the real world, so far the EU's regulations of Apple has shown Google that it can safely make Android a closed platform. Before there was uncertainty that Google didn't want to test. This is possible because EU don't care about "sideloading" and accept the security argument to allow gatekeeping by the device/OS makers.

Meanwhile Apple is having fun how to creatively pass the EU regulations while defeating every point of it in practical terms.

Maybe in a decade or two there will be something useful from this, but in the meantime it will be worse.
