I am a co-founder of Terrateam and we have made a pledge for OpenTF. I understand where you are coming from, but right now it is difficult to know what exactly to pledge as we want a dialogue with HashiCorp on what they need as well, if they want to donate to a foundation.

We just moved to a table format for pledges and brought back the commitments so you can see them: https://opentf.org/
