I am 100% with you in general, but this feels more like the Windows Defender launch than some fully cynical power grab. That is to say - Microsoft gets a lot of grief and work from windows installs getting taken over / viruses / etc. For users who don't pick up their own protection (and don't choose to turn off the default windows protection) this feels like a better default. I don't trust Microsoft, but you are already exposed to their manipulations when you are using their OS - and this will help protect you from other manipulations.
