I'm using their ecosystem indirectly, not locked into it, with an option to leave whenever I want, with a superior computation model (in the case of Pulumi), that's the point.

If Hashicorp changes all the licenses of the providers they maintained, then that's fine -- I have no right to demand free work from them.

I would be worrying a lot more if all my automation was built on Terraform, Consul, and Nomad, though -- and I'm glad I didn't do that.
