WOTC has been on a downward trend since the Hasbro acquisition.
In the short term all the franchises have proved incredibly popular (just like in Fortnight), but in the long run I think it means the death of the game (just like where Fortnight is headed).
The game(s) are more popular than ever, especially D&D
Also: Yes, Hasbro did some shit, but they also had to relent and CC their SRD. This all happened years ago.
I say this as a committed Pathfinder player who hasn't seen a good reason to return to D&D (PF2e is good enough). D&D is doing numbers and no one cares that us nerds moved on because of weak tea from the previous decade.
It's their house now, and it's fine.
Several of the top D&D people who were advocating for players resigned around this time.
WOTC/Hasbro since relented under this pressure, but the bridge was already burned. My group hasn't played a D&D campaign since. We switched to Pathfinder 2e and found that it was a better system altogether.
Popularity is not a reliable metric.
Every year seems to be the best-selling year so far. Magic: the Gathering is Hasbro's primary revenue source.
And look, I don't like the sheer amount of product they're pumping out every year now. But I realize I'm clearly in the minority opinion based on sales.
