Bare in mind as well, if these online providers store or transmit files through other countries, they are subject to those rules as well (which is signed off by the customers("you") in the EULA that probably didn't read). Using some of MS' office suite means your sharing telemetry with I think over 800 "partners". I wonder how many "partners", info is shared with for those that use OneDrive that I think is baked into modern
Windows now?
And while some on here (I don't think they have contributed to this thread, but they are still active) believe that they have nothing to worry about with what they store, so why bother worrying about this specifically, that misses the point of the issue. Can think that if one wants to, but not a good thing, regardless if one has something to hide or not.
I often wonder why people don't handle it themselves. It isn't that hard (3rd party vendors just don't have any reason to care like the owner of said files, or at least the owner should care, otherwise why be doing this in any capacity), relegating it to a 3rd party doesn't work out at all. They still have issues with malware, they still give up your info at the drop of the hat, they still forget to turn off known vulnerabilities after they change a setting (that is closed off by default for the same reason) and they can still get your
computer infected using their own backup software (at least with regard to those dental offices that used a particular 3rd party backup solution).
