Ha ha, what?
They're criminals. They fucked shit up for money and then held the company hostage. If they don't pay, the ransom group WILL release the data. If they do pay, they might release the data, but they'll just quietly sell it rather than just dumping it.
They're a business. It took time and effort to break in. They want to be paid. If you stiff them, they're going to fuck you in the ear. If they sell your data after the fact, what are you going to do? Complain to the manager?
They're not professional, they're extortionists that don't give two shits if they're respected. They steal what's previous and threaten to dump it or sell it back. Their reputation is already shit, why would they care otherwise? This is such a naive take.
