Microsoft and 3rd party A/V providers

Found this article and began wondering whether Microsoft is indeed behind some or most of the issues with Norton running on Windows 10. Kaspersky seems to think along those lines. You be the judge!!

I don't think there is any doubt that Microsoft thinks of itself first and if someone else's product does not work properly or at all and MS has a feature built in I doubt it gets much priority to get the cause fixed.
