Why would Discourse's business model work when Stack Exchange v1's failed?

What a fantastic and intelligent thread this is. It it worth it to restart again here and see where Discourse stands 7 years later? It seems like it is in a very good place, but I’d like to see if indeed that’s the case. Seems like the Wordpress.org/.com model is working.

And the recent Discourse for Teams launch is a validation that the core can be used to venture into evolving collaboration markets dominated by giants like Slack and Microsoft.
