Cloudflare is running the largest and longest denial of service attacks in the history of the internet by acting as arbitrary gatekeeper to important government sites like congress.gov. I haven't been able to load it in years.
Lacking lived experience re: discrimination is something that's pretty common. I hate to compare my entirely optional 'software veganism' struggles with real discrmination issues, but just because you don't experience discrimination doesn't mean it doesn't happen. I go to online stores, government services, even places of recreation and I get denied service because I have to tunnel to avoid my ISP's unethical practices and I don't use a cloudflare approved browser. It feels bad.

Xfinity is not MITMing HTTPS sites! You control your trusted CA list.
You don't need to allow JavaScript to run on all sites.
