This was a post by Brad when asked about the possibility of shutting down an MMO if it were no longer profitable. He explained why this wouldn't need to happen with Pantheon. The post was in 2016, but I think the points he makes are even more relevant today in 2020.
This is why I am comfortable investing in Pantheon.
