It is in the very article this thread is about
I read the article and didn’t see that. The article talked about preparing to donate the code to CNCF.
My mistake. The announcement page talks about CNCF plans, https://opentf.org/announcement. I got myself onto the manifesto page, which doesn’t currently mention CNCF, https://opentf.org/.
Moving OpenTF to CNCF is a great approach. It will be helpful to be able to share this news.
