@gabek @laurenshof @aral @Mr_Teatime There are lots in the privacy space alone, with Proton and Fastmail being the largest, apart from mainstream options and those offered by domain registrars. Hosting email is not something easy though, unlike an ActivityPub instance. Regardless, I don't rule out the possibility and agree with you, but I just personally feel that the fedi has way too many potential big players, since unlike email hosting, any person or company can easily spin up an instance.
