There's an explanation here:

Basically, looks like they wasted a lot of time building collaborative knowledge graph features, and then realized no one really wanted them. By that point there were mature single-user alternatives and they were no longer competitive.

That's right! We made a bet on collaboration because everyone was already doing single player.

Now there are even more single-player tools, they are all still competing with each other, and implementing the same features, i.e. wrappers around GPT-3. Super happy with the bet we made :)
