You mean in a few years there'll be only 3 or 4 free mail providers with e2e disabled for convenience[0] and data broker objectives (as a mean to pay for the service) and only a selected few can federate (because hey, spam or something) ?
Like Mastodon, Matrix has it built-in in its principles that a federated instance can prevent being contacted from another (this is the whitelist setting). Feel free to correct me, I am not 100% sure.
