On the Edge of disaster

One of the main reasons for subscribing to Norton Family is for parents like me to be able to block kids' attempts to surf porn.  Now Norton announces that they can no longer control Edge?  And they tell us that we should "use another browser instead"?  But when we ask "how do we prevent our kids from just running Edge" there is no good answer-- Microsoft makes it impossible for Windows 10 users to disable Edge.  So Norton is actually suggesting that parents should just discourage kids from using Edge?  Seriously?!!!  I understand that Microsoft is preventing Norton from monitoring Edge, which sucks for everyone, but if that's the case then I think everyone needs refunds on their subscription fees because the product is essentially useless at this point and must be replaced by a competitor that can actually protect the Family.  I wish I could replace Microsoft instead, as it sounds like a manipulative and anti-competitive business practice on their part, but unfortunately that's a lot harder than just replacing my parental control software...
