It's a little tongue-in-cheek, but as you can see elsewhere in this discussion thread he mentions this himself on his own X account:

"get asked the same about terminals all the time. “How will you turn this into a business? What’s the monetization strategy?” The monetization strategy is that my bank account has 3 commas mate."

Take a good guess where the three commas come from.

Money begets the freedom to work on causes. Monetization was always a core part of Hashicorp, rather than being a bolt-on after years of OSS. Which is a good thing. (I was a customer of the first commercial offering from Hashicorp, their VMWare add-on for Vagrant)
