I disagree, I think that with 5e DND got super lucky, because they hit upon an unexpected gold mine, with the pandemic, stranger things, and Critical Roll all happening at the same time. Instead of recognizing this as a valuable opportunity to move forward TTRPG and usher in a new renissance on that front, they instead got high on all the money they made for reasons largely beyond their control and assumed it would continue forever, because the corporate suits considered their players "undermonitized" their quote not mine.
I was suspicious of the 1D&D crap moving to a subscription model anyway, so I am quite frankly glad about this.
