You’re ignoring the context of the comment here. The parent uses an example of Twitter doing better after laying off 81% of the staff to suggest that other companies could do the same.

While you’re right in that the platform has its uses, other companies cannot do the same. Which is why it’s important to talk about objective success metrics. Sure if you want to fire 80% staff at Microsoft and have a transformation where they only cater to half the user base then they can do it. But they will also not be taking in the same profits as before.
