Companies like google collects, stores and shares data on you.

I don’t want someone looking over my shoulder analyzing, interpreting and announcing to the world what I do all the time. I also don’t want a permanent record of that to exist. It hurts me when done to me. It hurts society when done to everyone. An example where it hurts you is when you go the insurance company and they deny you or make it expensive cause they have data on you, your behaviour, health and opinions.

It will also be used against you when your government decides they are no longer going to respect human rights or cracking down on the citizenry. They migh feed a big pool of data to an ai and the ai gives you a shitty social score. Nothing is forgotten and it will be missused and missinterpreted. Never for your benefit.
