[whym]

I don't think any fork was deleted. 3.5k forks as of now vs 3.4k forks in January: https://web.archive.org/web/20220129022012/https://github.co...

Many people won't notice some of their stars having disappeared, but many would be surprised to see their forks deleted without their consent, especially those that are not merely a mirror. People can have diverged forks after adding substantial changes without feeding them back to the original for a variety of reasons.
