For AI companies the access to the interaction is very valuable, that explains the price difference. It is data that the competition does not have access to. Of course they are storing that data for model training purposes, that's the whole reason this exists in the first place. They are subsidizing until they get their quality up to the point that the addiction is so strong you won't be able to get through your workday without it. And then surprise the per month access fee will start to rise.
