ELI5: In light of the Dropbox hacks, why do so many hackers just dump passwords on the internet?

Many hackers, even black hats, don't always hack for profit. Many do it for fun, or to see if they can. Additionally, many do it and then do massive info dumps like these ones, because they force companies to change their policy to make things more secure. Dropbox knew they were hacked YEARS ago, but they didn't force sitewide password changes until this week when the info was released. The timing was probably the hackers getting sick of waiting and forcing DB to max some policy changes.
