I mean apart from the fact it's not sourced or whatever, it's standard practice for these tech companies to run a massive loss for years while basically giving their product away for free (which is why you can use openAI with minimal if any costs, even at scale).
Once everyone's using your product over competitors who couldn't afford to outlast your own venture capitalists, you can turn the price up and rake in cash since you're the biggest player in the market.
It's just Uber's business model.
