The triangle says Confidentiality, Availability, Integrity. While your concerns are 100% valid, we need to remember too that setting up access in restricted ways and inviting users to understand the protection and remove the correct barriers, or implement the concerns necessary to interact with those for themselves, always runs the risk that some users will find your protections cumbersome and instead find a (totally incorrect) way to baffle them, or otherwise even route around them entirely mooting any efforts to secure a platform. And every time I hear this played out in conversation, the answer is "that's on them!" But it's clearly a balancing act, it's a trade off; tautologically, when you make the service less accessible then... it is, well, ... made less accessible. Besides facilitation of the secure access also sales conversion ratios will depend on that accessibility. The crux of your argument stands, the defaults are too open, and we need to do more to ensure that naive users aren't handed a loaded gun to aim at their own feet.
