They don't provide the trained model do they? That would take millions of dollars of GPU time to train. This safely keeps it out of the hands of the rabble.
Yes, but that wouldn't stop Blizzard if they wanted to use it.
But what would anyone do with a bot that beats almost all human players in Starcraft? Its was mainly a demo to show how far they can take their reinforcement learning algorithms after AlphaGo.
AlphaFold has much greater utility and its trained model parameters can be downloaded.

Same with AlphaFold.
Now people here complain that they don't sell APIs to proprietary models like OpenAI. They are a research lab after all.
