Asonderu What about your insights?
My insight is this; unless you are provided irrefutable and absolute proof that something is as it is claimed, then there is always a risk that it is something else. That doesn't mean that it is something else, just that it could be.
Consequently, in deciding whether or how to use some service, you need to assess the risk and make your decision accordingly. It may be ok to use a service that has some risk, but you might want to take care of the sensitivity of the data you expose to that service.
