I don't think you are quite getting the scale of it yet. They have all your data, they know your health records, your financial transactions, they know who you talk to*, and about what. The problem with kids is that they don't produce as much incontrovertible data. Quite inevitable that they will wish to extend their reach to controlling and shaping your children, as they control and shape you.
Don't think there's some level of proprietary decency embedded in the system. There isn't, that's why they spend so much effort persuading you that fascism is best. So that no social level structures can interfere with them doing whatever the fuck they want with you.
The choice is stark. We have to become socially cohesive and fight for real rights and freedoms, along with meaningful regulation, or accept digital slavery. The direction of this particularly supine and pathetic country is meek capitulation.
* I did this experiment with some old services (outlook online etc.), where I had log ins that weren't tied to anything else. Had been created in different times. Couldn't be traced to me individually or one of my IP addresses. Tried various ways of logging into them without giving that sort of information (tor, not authenticating with another service that was 'known'). It was essentially impossible. Where another email address was also not known, it was impossible to use this to verify a log on. Basically being passed around until you compromise your identify by connection or known service 'for your security'. Which it is of course nothing of the sort. I do not think any of us are safe, until we take steps to protect ourselves and those that we care about. The sort of ghouls who own and run these services rarely let their children access the public internet.
