While you can write an automated tool to consume all their tokens, I strongly suspect most users, like myself, are not doing that. So even if Anthropic loses money on a power user, they profit overall and keep public sentiment high by not alienating users with restrictions. It's an optimization problem of making a profit off the average used while staying low enough to attract customers, even if that means some users cost more than they pay.
More users spinning up OpenClaw means that balance starts to shift towards more users maxing their tokens, thus the average increases, so I think their explanation makes sense still.
