No. This shows the same misunderstanding of the ttrpg market that Wizards execs are making.
There are no "competitors" to D&D. In the ttrpg space there are people who play D&D and people who don't. People who play other games also usually also play D&D because that's how it works.
You don't get more D&D players by crushing other game companies. You get angry D&D players who are mad about Hasbro destroying one of their favorite other RPG companies and deciding they don't really want to spend money on D&D anymore.
It's a fundamental misunderstanding of the ttrpg market to think that D&D can grow if they squeeze out other companies. It's a TSR level mistake in how the rpg market works.
