I haven't thought about it at all as to how Google would fix their problem. Still, they've introduced a component into the Internet ecosystem that has been found to be abusable and they are accountable to install the forcing functions to prevent that abuse. To depend upon user education is simply irresponsible.

The idea of forcing functions is well known in organizational/system theory.

Another way to think about this is the recent notices that Java (and at other times Adobe Flash) has recently introduced a security flaw where people using their computer can have it hacked into (Apple suggests removing Java unless you really need it).

Just as we would expect Java/Oracle and Adobe/Flash to fix their security flaws so should Google fix theirs.
