I'm not being snotty. Terraform is not the best choice for every organization.
Rather, Terraform does not add value within every organizational structure. Not adding value is failing. Having a negative ROI is failing.
None of these infrastructure tools are perfect, and the ways in which they are imperfect mean that some are better or worse matches for an organization's needs.
Therefore your initial statement is oversimplified, presumptuous, and ultimately nonsensical. A logical reframing is "if your organization does not match Terraform's strengths, then your org is the problem", and that is clearly not true.
