Apple is not a solution, it's a stop gap. They will still want a copy of the messages after it, and all your other data. And the reason for the huge backlack, is that this stop gap will actually make it easier for them to request more afterwards, because the infrastructure, the proof of concept, will already be there and running. And it will cross to other providers: "see Apple does it, so clearly it's Signal that's being protective of criminals, we should impose them to do the same thing Apple did with no issue".
