Yea, they sent an email regarding this change not too long ago. Obviously they didn't spell out, that they will do this, they only said that there is a change in the TOS, what you can read here and here. If you agree to it, you don't have to do anything. Not everyone read those emails, let alone go to the link provided and actually read the changes. Which can be "fatal" and surprising at times as Gogol's example shows it pretty well. If you don't take action, they assume, you accepted the changes. They not only assume, but that's the general procedure. They send out an email about the changes providing a link, if you fail to let them know, that you don't agree to the changes, you automatically accept them, according to them.
