I know most HN commentators are thinking about Terraform, but I think this change was done with Consul and Vault in mind. Plenty of companies (including my employer) have been building fully monetized software using Consul and Vault under the hood and not paying them a dime. We're a company that's valued/market capped in the Billions btw and I know plenty of other large software companies doing the same thing.
Don’t think it’s targeted at Vault. Vault has APIs so in the enterprise, you can self host and a vendor can manage vault through the APIs. Terraform specifically is built CLI only in the OSS so you have to repackage the underlying binary and hence are subject to the license as a vendor.
if so, that's similar to proprietary programming languages. Not a thing. The community can just agree on a similar but open alternative and the original company is left behind. That's why all languages and frameworks are open-source with permissive licenses.
and if not, if it's just about the hosted / managed parts - then what exactly is it that I can use wrongly? Terraform Cloud / Enterprise was never open source. There's nothing I can self-host and charge users for...
