I don't care how many points of presence Cloudflare has if the performance is worse.
Do you have any data that supports your claims?

So, if we don't make our websites available in languages used by oppressed peoples, if we don't make sure it's very low latency, and if we try to filter out abusive users, we're making the world a worse place. Not just leaving the world in a bad state, but actively increasing the harm done to the world, just by making a website that not everyone can or wants to use.
Not only do I not buy this argument, it makes me want to support Tor less, if for no other reason than blatantly ignoring why the captchas were put up in the first place.
The part you have a problem with, that it actively increases harm done in the world, wasn't even an assertion made by Tor.
If you use TOR to access services that can be directly correlated to your identity you are simply using a slow VPN at that point.
