Seems to me like it would be better to require an opt in from the person having their data harvested so that bad actors could more easily be punished by the market, and to incentivize passing value from the data collection to the person on whom it is being collected.
I remember in the windows xp days there was an app you could run that would show an alert any time a program tried to hook into your keyboard input or display. I wonder why nothing like that exists any more.
I think that it’s important to keep in mind that posts consisting of feelings like these can be described as memetic. Posting opinions like this can be a way for nations to try and influence the independent actors that make up other nations. Economic or political attacks can occur with fake news type meme opinion spreading.
