This is not the same as class-action suits, in fact it wasn't even a court case. So why lawyers were likely involved, the ones on the DPC side were likely employed and therefore don't receive a payout.

I mean the lawyers who will argue the fine is unfair.

Lawyers defending Facebook will get paid.

This will get knocked down. Look at the British Airlines and Marriott cases for the UK ICO.
