I am not a salesperson, but I did work in advertising for a while and this strikes me as an excellent pitch. I still think easy onboarding and a rebrand would be necessary to reduce friction, but I think you're onto something.
The name Mastodon is unfortunate, Twitter is a better name as Tweeting became a verb, not sure how to verb Mastodon without it becoming a lewd euphemism. "Hey I Mastodonded about that" erhm... you did what now?
How would you go about a rebrand of Mastodon?
Why does everything need to become a verb?
I have not seen people Linuxing or macOSing or iPhoning or Kubernetesing. Some nouns can remain nouns.
It doesn't need to be a verb. Really anything that isn't so coarse would probably be fine. Twitter is not a very good name because it's so feminine, but it's way better. Threads is a perfectly fine name.
Just let branding people do it.
