That’s an oversimplification of the issue.
The most critical game-breaking bugs were fixed within a couple weeks, but not all of them. It took a couple months before they were finally ironed out. Even after that, you would most likely still experience at least one bug per play session. And that’s on PC.
Most of the sustained outrage came from the PS4 and Xbox One players who had a massively unplayable experience, so much so that the game was delisted from the stores and refunds were offered. The game was just not a good experience on those systems.
I honestly don’t know if those versions were ever really fixed, since I played on PC and so I didn’t follow the console version progress. The eventual PS5 and XBSX releases were fine to my understanding.
