My perspective is this is my home network and this application is infringing on my freedom. I should have the right to monitor my network and my traffic. An application is a guest in my house/computer it does not set the rules.

The key is that if it's really your traffic, then you can easily reconfigure Firefox so that you can monitor it. The benefit of DoH is that if someone else is using Firefox on their own computer, you can't snoop on or hijack their DNS just because they're on your network.
