Also, one thing the numbers they published show is that the bits that are growing 10x YoY (and which they expect to get “worse”) are all the things that you get “unlimited” mileage off (even if you're a paying customer): repos, commits, PRs.

Things that have “usage based billing” (like action monites) grow closer to 2x YoY.

When there's a dollar amount attached, people don't 10x, because it's not worth it. They splurge when it's cheap, and unlimited.
