As an aside, it's amazing how much work Stripe has put into Sorbet. More than half of the ~100 contributers work at Stripe: https://github.com/sorbet/sorbet/graphs/contributors

It's actually the opposite: most contributors to Sorbet are outside of Stripe:

(I work on the Sorbet team)

Here's "git shortlog -sne", with Stripe employees (current and former) and email addresses removed. I've annotated with current company, if easily-discoverable: https://gist.github.com/muglug/a70b7316f92d05f9febbf56684a8e...

That list is a minority of all 166 in the original (and there may still be some Stripe accounts there).

Additionally all of the top 10 are current or former Stripe employees, and at least 96% of all commits come from current or former Stripe employees.

BUT there's also nothing wrong with this – in a similar project I created (https://github.com/vimeo/psalm), 90% of the commits come from employees at Vimeo. I was just pointing out it's good.
