I think it's indisputable that John Romero is only making this because of the Doom community. And I don't just mean that in the sense that the only reason he has modern tools to work with is because of the Doom community, although that is also indisputably true. In fact, I feel like he said as much - that the response to E1M8B, both generally and within the Doom community, was more overwhelming than he anticipated, and it gave him the idea to continue on and make the full episode. I think that says just about all that needs to be said about how important we are, to him, and not just vice versa.
If you maybe want some more objective evidence, after E1M8B was released, and there was the Noclip documentary about him, I (obviously) watched the footage like the Zapruder film, and noticed:
If you don't remember, I actually made a physical Cacoward and shipped it to him after he won one for E1M8B. And it showed up in the B-roll of a documentary about his new work in Ireland, totally unrelated to anything, apparently in a prominent award case, up at eye level...which means he thinks winning a Cacoward from Doomworld to be at least kinda a cool thing?
So my point is: John Romero is making a new Doom episode because of us, and in part, for us, and considering he's John Romero, I think he deserves some goodwill here.
