I looked at github /chef/chef and github /inspec/inspec and its the same as it was shortly after I left. The only changes are from the one person who carried over after the sale to Progress, and the contracting team out of India, with dozens are unanswered queries and pull requests from the community.
What really ruffles my feathers was when they had us define oss-practices (https://github.com/chef/chef-oss-practices), clearly nobody outside our small team read (or understood) those words and goals. It feels like it was work to make us look better in OSS in order to bolster the company sale.
There's probably some manager at Hashi right now trying to argue that they should offload TF maintenance entirely onto the community and they should pivot to hosting services and consulting and making money off of all that free work.
It's all good and "fun" on the IPO up.
(in x months we will rewrite the whole universe).
