Facebook settled a case for providing data to Cambridge Analytica. That was all about use of user data in ways that were not laid out in the Terms of Use.Do you know the # of cases that are currently before the courts on these terms of use, for the services they provide?

Google lawsuits against Facebook or Google and you'll see how often they are plantiffs in litigation.
Professionally I have been involved in two instances. One where a company did not live up to the performance standards made in its Terms of Use and another where a company contacted me about multi-user access.
