The ToS had no rules on misinformation at the time.
it still had rules about animal abuse, which this misinformation, had it actually been misinformation, would have lead to. while the removal reason could have been more clear, the justification was still covered by our ToS.
new rules created to back their talking points
the additional rules provided more clarification on what we intend to achieve with them, but they would not be required. based on what we know today the removal was neither justified by the original ToS nor by the updated ones.
The animal abuse alleged at the time was that there was supposedly no healthy vegan cat food.
While the section of the rules was the same (violent content), animal abuse was a separate sentence, not the one about visual depictions:
This is the exact same paragraph we have today and we had before these changes.
If there was no healthy vegan cat food then this would be considered content enabling animal abuse.
