Edit: I don't want to sound dismissive, so let me explain the difference. Anyone coming to the website will be using a computer of some kind, and even if they for some weird reason don't, the verb "compute" does give a hint at what a computer might be. None of this is true for "infrastructure-as-code".
The target audience for a IaC project is probably people who know what IaC is. Or even people who know what "infrastructure" and "code" are, separately.
But a person who knows what "infrastructure" is likely thinks of roads and power lines and sewage pipes. A "data center", which is what "infrastructure" roughly means in this case, isn't exactly the prototypical example of "infrastructure", or is it?
Right now, most of its target audience already knows exactly what terraform is and why they're abandoning it, although I agree that pivoting to explaining independently of that is a good idea
