Good point. I agree with that. The key point is that heavy users benefit from this model while light users are basically subsidizing them. But it's a distribution when everyone shifts toward heavy usage, prices inevitably go up. The $17/mo pro price is already set to compete with other providers. Raising it would lose customers. Other tiers are also carefully priced to match competitors. So the only move left is to prevent the whole distribution from drifting toward heavier usage. That's exatly what this ban does.
