Focused on the E2EE because that’s the most relevant to privacy.

I hope they also implement an easy way to verify the public key’s.

It should work like with Signal, SimpleX etc.
Not like it works with Matrix

Considering you can sign up anonymously with any email, is Mastodon about to become the next best thing or even better than Signal?

I’d say Mastodon is first and foremost a public social media platform where you post things publicly for everyone to see, and the private messages will be a nice privacy upgrade in the future. Signal is 100% E2EE all the time. Just by that fact alone I don’t think Mastodon will ever be a competitor with Signal, because it’s not really designed to be.

That ‘all the time’ is the operative factor. I imagine unless every instance set up by anyone comes with E2EE enabled by default with private messages, Signal will always remain superior. But yes, people should still only resort to Signal. I only think Mastodon E2EE DMs even by default in the future will be used in a pinch if Signal app is not available or if the web platform is the only thing one can get access to.
