I'm a data engineer, ofc I know that. But you were excusing it as if their service has costs. That's bs, because their reported earnings that done without whatever profit they are going to gain from this harvest of train data already were very profitable.

That's why I said you were in the wrong. Not because you expected them to sell everything they could, so did I, but because you justified that behaviour from the free to play model. That model exists in plenty games that are extremely successful without harvesting things beyond metadata.
