While I feel quite bad for future generations of players that will inevitably suckered into buying subscription services, endless reprints of books with tweaked rule sets, merchandise, and microtransactions on WotC's official tabletop RPG, I'm glad the hobby is relatively independent of what any company does, much more so than something like Magic the Gathering. Nothing WotC can do will ruin the game for anyone willing to pirate a PDF of the player's handbook and use a little imagination.
The article's claim that any dungeon master needs to buy the player's handbook, the monster manual, and the dungeon master's guide is completely ridiculous. You can find the stats to monsters online on a whole host of websites, and the DMG is basically just advice and little minigames. You're probably better off taking inspiration from it at best, and house-ruling things like chases. No wonder 5e is having a dungeon master shortage if DMs are expected to shell out so much cash, as well as host a game a lot of the time.
It’s funny because the way I play DND is I glanced at the rule book one time and then I have my players roll stuff based on how funny it is to me, I’ve been running the same campaign for two years
Edit: worth mentioning I’ve never paid for anything DND related
