Re: Why = money
"Circumstances will determine whether the data is truly stolen or if there is a usurious paywall blocking its access."
You are not talking about the same thing we are. Stolen data does not mean pirated data, but rather the result of clearly illegal theft of that data, whether that is a breech, GDPR violation, or anything else that is clear but can't be reversed. This isn't about data that's in a paid-for journal. Incidentally, if someone did get a copy of that data without payment, one couldn't figure out whether they had or not, so the stolen label couldn't be reliably assigned.
