This is very alarming. If web session data will never be included in telemetry, why do some people have to ability to query joins? That means it can happen. Why does this small set of people need to access my web session data? I don't use Firefox regularly, but I have it installed on my computers. I think I'm going to uninstall it completely. This stuff has become more and more common, and is totally unacceptable.
