I hate it as well, but here's my best guess as to why change it is unlikely: Most of their revenue probably comes from companies, which virtually always issue company emails for their employees. In that case, you'd still have the problem of multiple logins (admittedly fewer, though).

If you've ever used Discord with multiple logins, it's actually not seamless at all. You essentially switch accounts and are only able to see the chats associated with one account at a time.

Thus, not only would it probably be a non-trivial technical challenge, but they would also need to put in additional UI and UX work to make the experience better than what Discord offers. And all that effort probably isn't worth it when their money comes from customers who won't benefit from it.

Ultimately, I think if you want to run a chat but aren't providing the members with emails, you probably shouldn't use be using Slack.

I don't know about Discord that was given as an example earlier for a single login, but most tools allow you to have multiple emails with a single account (eg. think Github which most of the same companies use).

There is nothing stopping Slack from doing the same while still getting money from companies needing their service.

You're right about the multiple logins with discord critique. A seamless switcher would be nice to have.
