Yeah, kinda.
TTRPGs is not a big enough money industry to maintain itself at its current level without leaning or pooling on other industries to create its moneybase.
But how much of "the current level" is already factoring the massive buy-in to D&D? Is there some reason to believe if you pull out WOTC and the companies directly dependent on them (i.e. who make their living primary on D&D supplemental products) that the rest would suddenly have a problem? Seems like pretty rank speculation. You can maybe argue there'd be problems over time as that gateway stopped feeding new people into the overall hobby, but even that's based on the people who move to other games from D&D is significantly larger than peopel who start with the others in the first place, and in any case it'd hardly be immediate.
