Then it's a good thing it's being decided in a court. Which is what provides checks and balances, AWS says "You violated our ToS, we're cutting you off", "Parler sues and says 'No we didn't and here's why'". If Parler wins and can prove that they were unfairly targeted, then they can sue Amazon for damages. Which is what keeps Amazon from unfairly applying its ToS. And if they can demonstrate irreparable harm, then they can get an injunction forcing AWS to restore their services immediately rather than waiting for the court case to be decided. But I think the best they could do is present monetary damages, which the court could decide AWS is able to pay.
