iOS won't let websockets work without https so I think you can't do things like self-host jitsi meet. Many appliance type devices won't allow adding self-signed certificates either.

To be fair, you couldn't self host jitsi meet in 2003 either

Websockets didn't exist in 2003, so that's just a case of higher expectations.

Back to plain sites and not websockets, browsers didn't go through a missing https warning process in 2003 either so there are higher barriers and not just expectations.
