I think you're just digging yourself into a hole with those kinds of answers. The answers are more likely to be "No" and "Yes" in that order, especially for the data feeds that are getting cut off. But there is little possibility of us as end users getting hit with a suit for either breach of terms of use or the CFAA (I don't believe I've seen it referenced in the thread yet, but it's relevant). That may not be the case for the entity that is actually creating, operating and profiting (call it a contribution, a membership fee, a subscription, I'm not sure the distinction would matter) from the tool/browser (again I'm not sure it actually matters what you call it). The more I've come to understand how some aspects of the tool/browser works, the less comfortable I am with it.

I think your direction or suggestion for users to sign up for GTC accounts was a huge mistake, and while the other providers who have plugged up leaky data feeds may have been content to just plug the leak, I now have my doubts that will be the case with the creation of GTC accounts, especially if there were a sufficiently large number of them. Those accounts being cancelled today may be only the first shoe to drop.
