This is happening only because the DMA exists. That’s regulation. So i guess the optimistic view here is that finally regulation is catching up to the tech giants.
The pessimistic view might be that big tech found a way to weaponize the regulations against each other to the benefit of no one.
A while ago there was a prediction about the true intentions of the russia negotiating: they want to stop Ukraine from succeeding as a state, since that would be a bad omen for a neighbouring kleptocracy.
If this prediction comes true the outcome you describe is actually very unlikely, because the russia would rather continue fighting just to keep the region in shambles.
