We are in some sense a competitor too, alongside Spacelift, Env0, Scalr and a few others. Our product is built differently though, Digger is orchestrating terraform jobs in your existing CI instead of taking over the whole CI stack and effectively duplicating it just to run terraform. We built it this way almost by accident; our original product was very different (think "heroku-like UI for AWS" that generated and ran terraform on the server) and this is how we arrived at what Digger is now. Luckily we don't seem to be affected by the licensing change as we neither embed nor distribute any of hashicorp's code (it's on the user to set up the right version of it in say GH Actions).

Anyways, fully agree that if you have a great product, you don't need to make such moves. We designed our product the way we did purely out of technical considerations - it didn't seem to make any sense to duplicate the CI stack. But it looks like this whole idea behind Terraform Cloud of having an "infra-specific CI" was driven exclusively by commercial interest. You can charge per minute! You can charge even more per resource! Now it's catching up with Hashi; so they have to make such defensive moves. If the product made sense technically, if it was designed the way someone would design it with no commercial considerations whatsoever, they wouldn't have to make such moves.
