It’s got a good bottom-up culture focused on empowering engineers to build stuff like React and ship changes to the social media platform on their own initiative (especially when those changes prove effective in improving key metrics in A/B testing). This same bottom-up culture leads to a lack of oversight on potentially questionable changes, and also means there is sometimes a lack of ownership and investment in fixing issues that haven’t gotten media attention (because no team decides to work in the fix). In recent times there has been quite a bit of investment in improving privacy but it feels a lot like trying to patch over a broken foundation.
