I understand why Google would run Gmail for free.. it’s signals for their ad machine even if they don’t literally push the contents of the emails themselves directly. I mean the metadata, connections etc is valuable for ads intelligence.

But I toss my otherwise public git repos on GitHub.. if they weren’t handing out for free, I’d have hosted them anywhere else publicly as well. What do they get by hosting my _private_ repos for free? Did they explicitly say anywhere that they are training models on code in private repos? That’ll be a dark pattern hard to miss out here on HN!
