From what I’ve been given to understand, the federal courts still have to approve the change of rules. The FCC is not allowed to just change rules willy-nilly. Even with the Republican stacked scotus there’s a chance that those rules will be nullified. In fact the court case could drag out till 2021. By which time there could be a different president and the FCC could have a different head of the department which would make the whole case problematic anyway.
