How exactly does Tor replace the ease of publishing something with Dropbox?

I guess he's referring to the fact that you can run a server behind Tor at an onion address without needing to forward any ports.

But that's not really the same problem.

You just run a web server in a hidden service, it takes less than five minutes to set up. People without for can still see it with onion.to.

That's not answer to the parent's question. Tor has very little to do with the ability to host your website by just plopping HTML into the Shared folder you used to have on Dropbox.

Please don't recommend that random non-tech folks do this. It is VERY VERY difficult to set up a hidden service correctly.

A better comparison here would be neocities

What's a hidden service?

AFAIK creating new accounts didn't give you a folder "Public" anymore since a long time ago, but they still existed with preserved functionality for old users.

I'm an old user and mine disapeared a huge amount of years ago. I'm quite surprised by this announcement.
