In my opinion, the difference with Google is that Google is actively using your data and you’re giving them a lot of it. For Cloudflare, what do they have exactly? Depends on what services you use, but really all they get from me is the list of servers that connect to my domains. Google does that too if you use 8.8.8.8, or if you have any of their hardware that overrides router DNS settings like Chromecast and Google TV.
Edge and Chrome are basically very similar at this point. Firefox is my browser of choice these days. It’s not perfect, but at least it isn’t anti-adblocking and doesn’t freak out when I block 8.8.8.8 like Chrome and the Google devices in my house. I’m moving away from Google as they move away from not being evil. Moving to self hosted stuff as much as I can for photos, email, file storage, and soon, home automation.
