Really ? I can think of QT - but that's such a huge body of work with some very specific use cases in which it doesn't really have competition (aside from DOM based shell for UI maybe, but that has it's own problems and is often a hassle to get working).
In this case Node is established, Deno is going to have an up hill battle to gain that mindshare on equal footing, adding a licensing restriction would probably kill it off the ground.
