I'm imagining within any group of legal experts there's disagreement on how to approach risk/liability and manage it, if it is unavoidable. You need a dictator :)

The parent is probably right: Not a nefarious agreement, but it is some kind of irony that the service exists to help expunge your digital existence in many places and they have you agreeing to use your commentary (satisfaction?) as a means to market themselves.

If you were so happy with their service, I wish you could submit testimony in an explicit area of their site. I left an earlier comment and erased it: I'm not a fan of "implicit" we-can-use-anything-you-do agreements. I wish it were more transactional. That's why this service could be fantastic: It's alienating and exhausting to live in the digital public where every influencer/company wants to use your existence for monetary gain.
