Unless this whole setup is self-hosted (which I doubt), it's also uploaded to some data lake of a company which is in business of profiting from information.

Intelligence agencies are really heading into a golden age, with everyone syncing all the data they have to the cloud, in plaintext. I mean it was already bad, but it's somehow getting worse.

The thing about that is the benefits, saving a couple minutes a day and not having to click to different windows where the information is stored, is apparent and intimidate whereas the harms associated with loosing most, if not all your privacy and security isn't felt in the same type of immediate way, so the dopamine of the positive effects completely overwhelms. It is hard for many people to be able to weigh different cost/benefit in situations where it is so one sided on the immediacy spectrum.
