The purpose of the name change fee is to discourage touts from buying up all the cheap tickets, and selling them on. If they buy tickets for a tenner each, and sell them on for 60, then a 30 eur name change fee isn't going to be a major problem.
I don't think Ryanair would object to bona fide name changes, where the original person genuinely intended to fly, as opposed to intending to sell the ticket on at a profit. The problem, is how they'd go about efficiently enforcing that.
