I’ve been using tuta.io ever since I created an account with them so the change to tuta isn’t entirely new to me. Having said that, it is indeed infuriating that they do not give you the tuta.com email for free automatically, because then anyone who signs up with [email protected] essentially has a more legit email address than yours. Protonmail gave out the proton.me domain to all users for free, even to free tier users. Hopefully this generates enough noise for them to change this.
