Virtual tickets probably make decent money and I think most confa want to clean up the long-lived video before putting it out. Low incentives to stream for free it seems.
I've not been part of lot of conferences, but both Emacs conf and Nix conf put videos up pretty much as soon as they're presented.
But if the conference is independent and the aim is to make money, I get it. Conferences with aim to socialise/promote to/the userbase tend to make it as low friction as possible.
