The FTC has investigated what personal data ISPs collect from their customers. However it is thinking in terms of regulating how ISPs can use that data, rather than whether they can collect it. In general, that choice is the ineffective choice.

If you can find a way to tell the FTC, "Limit the data ISPs can collect!", that would be useful to do — and I would be glad to post here the way to reach that agency, if it does not require running nonfree Javascript code.
