That's true to an extent, but the corporate presence of Hasbro wasn't felt as much until recent years. I mean, certainly, they probably had an influence on edition changes, from 3.5 to 4E, and then the "starting afresh" of 5E. But they seemed to let the game designers design. Meaning, they didn't "George Steinbrenner" D&D. I think that changed once D&D's popularity soared five-ish years ago.
I feel for sure the die was cast with 5e, and once it hit critical levels of success, its been coasting since.
