Policies matter. Cloudflare (US) is for now not too widely criticized. How about using a DNS server by default in lets say Russia, Iran, one that does block things by default? Seems suddenly like not such a great idea. This is to illustrate the point that policies do matter.
Real examples are problematic. Otherwise discussions on “is this or that blocking ok or not” risk the technological neutrality. Best to think this through before such issues come up.
Let’s speculate for the sake of discussion that Cloudflare starts blocking Donesk region too (similar to how Let’s Encrypt did). Now what?
Option A): Keep using Cloudflare.
Option B): Stop using Cloudflare.
Option B might risk legal issues for supporting to circumvent sanctions or weird law of some countries (such as US) which unfortunately are apparently enforced extraterritorial, in many regions. Too many to be able to ignore these in theory if one would want this.
Choosing an organization with wide power (such as blocking) over the operating system is a huge decision.
Too big an issue. I consider this ticket a blocker.
