This is genuinely concerning to me. The www and various systems, such as email, should be agnostic to whomever I am providing my details to. If I purchase a new SIM I expect a number where I can make outbound calls, receive inbound calls and use data without worrying about any "lists". Email should work in a similar fashion but as we know it doesn't, and there are various systems in place such that it's a game of roulette if your email reaches its intended target, and worse of all to me it's opaque, there's no way to know how likely it is or the various processes that may prevent my email being received by the other party. And for systems that are critical for communication we should not allow them to be put in any type of "allow"/"deny" boxes and no domain should be either trusted or untrusted, after all Gmail can be a huge source of spam, but it seems those who provide users control and privacy are considered an adversary which is really sad.
