Demanding more regulation isn't going to solve this problem. Demanding that your therapist and family members abide by some sort of "regulation" just ensures that will only use software that is formally "certified" to meet the regulator's standards.

Microsoft has the lawyers and marketers to ensure that they can meet any regulation the government wants to throw at them.

Linux just solves it and distributes the solution, fast and free, to anyone who wants it. Nobody has time for regulators, so even though it is more broadly scrutinized and more secure than anything Microsoft will put out, it never gets "certified" by regulators.

You can best secure your privacy by pushing your therapist, your family away from Micoshit.
