I have never used them. Have heard of it though. You would have to read their new terms of service to know what is going on. Usually you have advanced warning about stuff like this but most people do not read the TOS. They just agree to it and go on. It is the same with changes. And then something like this happens and it is like "what the crap" but they told you - you just did not bother to read the terms.
And I do it too. The terms are usually tiny print. Several pages. And long drawn out boring hard to understand technical garble. So people just tick "agree" and move on.
