Clearly, I am not typical in any regard in these discussions. First off, I've never played 5e, in fact the last true D&D I've played is 3.5. I was in the process of publishing a Japanese horror setting, but with 3.5 dead (off the shelves at the time), 4.0 not yet released, I moved to Pathfinder. I've since played, designed and published for Pathfinder and Starfinder. So, I already left. But I am in the process of wrapping up my first D&D 5e Spelljammer supplement intended for publication at One D&D, through the DM's Guild. So I am re-entering D&D on my own, without any encouragement by One D&D, WotC, nor anybody. Not to say, I won't publish more for D&D, perhaps I may expand upon the Wildspace System I've developed for the product, perhaps I may do some one-shots or full modules set there, but I have no plans to stop development of Starfinder which is where I spend most of my design time. I prefer hard sci-fi to science fantasy, and prefer that to Spelljammer fantasy, but I can develop for all.
So there's nothing One D&D can do to attract me, which doesn't matter since I came back on my own to release a publication for it. I am participating, but I probably won't be developing a ton of content, just a dabble or two for now...
