Draconian OS W10 putting kids at added risk?

MS REQUIRES you to use their privacy obliterating online account in order to be able to set up family filters in W10. Does anyone else find this to be completely and absolutely unacceptable? The content filter was a fairly helpful tool. Now MS has removed it from W10 unless you pay their ransom and create an online MS account.
Has anyone found a workaround other than selling your soul to the online account? Honestly, with all of the things that suck about W8 and now W10 I am considering learning Linux.
P.S. Don't waste the bandwidth trying to tell me that creating an online account isn't that big a deal. It is.

I didn't know about the online account being required for Family Security in Windows 10. My kids have it on their laptop, which is still running Windows 8. I use local accounts on my home machines. I don't have a need for the Microsoft online account.

But in reading about this, i can see the value. They can now use this account as a roaming account, across multiple devices and computers and you retain the settings. As a parent with multiple devices, this is an advantage.

I can see why some people would hate it. I'm not sure I hate it.
