I think this is a really bad look for Sebastian. He started babel and made the most contributions overall, but he hasn't been involved in the project for 5 years at this point. He left to join Facebook and babel would have died if it weren't for the efforts of Logan, Henry, Nicolo and the other contributors.

The original post on the babel website was written in response to him investigating the babel funding situation earlier this year, and so the babel team have made changes to make the situation fairer in their eyes. This apparently doesn't go far enough for Sebastian's tastes, so he has publicly called out by name one of the contributors who he feels doesn't do enough to justify their salary. The metric he uses for determining this is the number of github commits and comments that are shown on that person's profile. This is not a fair measure of someone's contribution to a project, and it's exactly the kind of behaviour that Sebastian would criticise if any other company was evaluating people in this way.

In the meantime, Sebastian has started another competing project, Rome Tools, which was recently VC funded.

The whole thing stinks. Will Rome Tools employees get called out and shamed in public if they don't have enough visibility on their github profile?
