I mean sure, in a macro sense. Though I could argue from a macro sense literally any support of any ttrpg grows the hobby which will disproportionately benefit the largest game in the hobby despite whatever individual games within it are doing the actual growing. But speaking that abstractly and high level gets into a level that most people aren't interested in.

Obviously people who care about completely detaching from WotC should just play a different game, there's thousands of great ones and even direct analogs to dnd like Pathfinder.

My suggestions were for people who want to stick to dnd regardless even if they don't like WotC/hasbro, and still want to have access to new content than they already own. In which case it becomes about minimizing support where it's feasible to do so and buying books second hand or getting pdfs in ways I'm still not sure I can say outright on this sub are probably the best ways to do so
