Eh, based on the screenshots and claim that they're doing some trolling, it might be a teen or small group of hackers that happened to gain such a wealth of data and their first instinct is to "download all the data, we'll figure out how to sell it later". If they had shopped around for a nation state buyer this certainly would've been more covert and a bigger hack.
