Whoa. You're a crime organization. The data may as well "leak" the same way it leaked out of your victim's "reputable" system.
Yes, the data might still leak. It’s absurd to suggest that it’s not less likely to leak if you pay.
There’s a reason why businesses very frequently arrive at the conclusion that it’s better to pay, and it’s not because they’re stupid or malicious. They actually have money on the line too, unlike almost everyone who would criticise them for paying.
