I read the linked article and the latter comments, and frankly I have to agree with the original complainant and many commenters that MS has gone too far with its invasive 'Family Controls'. For mine, it should be a family matter/decision to implement, NOT Microsoft's. to have it enabled by default... and to have Microsoft monitor EVERYTHING on under 18 accounts IS creepy. If I had children under 18, I would be more concerned about this kind of data being collected and stored by another entity... like what if it's intercepted and/or hacked by less desirable entities for untoward and/or unknown purposes? And I don't just mean creeps with ill-intent.... advertisers and other corporations are notorious for targeting children with persuasive ads, etc.
Seriously, Microsoft has gone too far in Win 10: re data collection and storage, and sending parents weekly emails about their childrens PC/online activities is way over the top. First off, given how many people have their Microsoft email accounts hacked and/or tampered with, putting that information out there like that gives creeps another avenue of access to kids personal lives. Moreover, it ISN'T going to stop bad parenting! Parents who care about their childrens computer/onilne activities will have already taken the necessary steps to protect them... from themselves and others... and bad parents are not going to respond positively anyhow.
I once caught a youngster viewing online porn, but instead of ranting about how wrong it was and threatening to cut off internet privileges, we had a conversation that proved more useful. One of the questions I asked was, "Would you like it for other people to be looking at you that way?" and the answer was a clear and decisive no. I didn't really need to say much more after that and we agreed that it wasn't a good idea. I can't say for certain that it never happened again, because I wanted to show trust by not checking the logs, but I'd like to think we reached an understanding and that my trust was respected.
