Sometimes when you try a thing, you'll get it wrong, and that sucks. But that doesn't mean it's not worth trying. I'm not aware of any significant damage done by Twitter getting that one wrong, and the decision took place in an environment of increasing anti-Asian violence in the US[1]. I have a hard time blaming them for trying to do something within their power while there were real consequences for inaction and the jury was still out.
