In the Meta case from earlier this year, the Irish regulator that imposed the fines did not think it warranted fines at all but they were overruled by a European organization. When the national regulator who investigated the offenses disagrees with the punishment, I think we can at the very least consider it a legitimate subject of dispute.

The article also says that Apple has fought for years against a 1.1 billion Euro fine in France. What the article leaves out is that Apple has been successful. Courts have already agreed with Apple and eliminated roughly 2/3 of that fine. Again, clearly there is a legitimate legal dispute over a fine if the legal system determines the regulators were, indeed, wrong.
