In the long run few will care about this licencing change (as much as they should!) – business users will accept it, individuals won't take any notice, and competitors would get mired in issues as expected. Basically a win for Hashicorp.
But winning on positive changes beats licencing issues. Business users will go where the centre of gravity in the ecosystem is, individuals will too, and will prefer free (in both senses) solutions, and competitors will push this hard to all their customers. It'll be interesting to see Hashicorp needing to build OpenTF support into their products to remain compatible.
> So far, four companies pledged the equivalent of 14 full-time engineers (FTEs) to the OpenTF initiative. We expect this number to at least double in the following few weeks. To give you some perspective, Terraform was effectively maintained by about 5 FTEs from HashiCorp in the last 2 years. If you don’t believe us, look at their repository.
Wow. Even if most of this doesn't actually play out in the long run, that's some good support.
