I doubt deno could have funded its development purely from sponsorship. And Deploy generated real revenue (on its OEM/b2b side).
Jt is interesting to speculate on what might have been had Deno never been a profit-seeking company. But having worked there, I am reasonably confident in my assessment above.
I agree that should it need to be profit making then what’s e got makes sense. But hey, Node isn’t a profit making enterprise. Deno could have been the same.
