33mail is cool but the domain being the same & unique for each user removes the privacy element, and it asks users to make up their own addresses (and remember them), which can be dangerous. For example you might create facebook@dave.33mail.com, so it’s very easy to guess what Dave’s twitter login is or other target. With Idbloc (and apple sign in) the address is completely random and untraceable, and it’s impossible to tell which addresses belong to which users.
