My personal opinion is it was a company for crack monkeys. Consul, Vault and Packer have been nothing but pain and misery for me over the last few years. The application of these technologies has been nothing but a loss of ROI and sanity on a promise.

And don't get me started on Terraform, which is a promise but rarely delivers. It's bad enough that a whole ecosystem appeared around it (like terragrunt) to patch up the holes in it.
