That doesn't seem to fix the underlying problem -- they understood/read the plain english version, just not the terms.

Honestly (and I'm guilty of this as much as anyone), I doubt they even read the terms. Here we have this huge thread about contract language being hard to understand, but if one doesn't take the time to read through, understand, and _remember_ all the terms of the agreement, how can one act on that information?

Complex, perhaps, but it's a complex subject.
