I suppose there is one way that D&D's ubiquity is, technically, helping the industry at large, but it's a back-handed compliment at best: because Wizards can leverage Hasbro-level influence, its sandboxed and predatory online store for third-party material is partnered with more global finanicial institutions than alternatives like itch.io or Kickstarter. This means that D&D Beyond is a storefront available to creators in many parts of the world where other options aren't supported by any of the financial services available in their country.
