People will give away all their rights for something they perceive to be desirable. A group of British researchers set up a captive portal offering free wifi and the EULA had them agree to bequeath their first born child or their favorite pet to access the wifi and quite a few people agreed to it.

I'm one of the rare people who reads EULA's and the FB never sat well with me so I never joined. The windows 10 EULA was downright frightening, good luck if you clicked yes to that one, you gave away all legal rights right there.
