These two categories seem pretty distinct, and the second is pretty nebulous. What does "significant" mean here, and how well does that translate to the odds of me working on an open source project? It's unclear why Netflix and Cloudflare are included but, say, Facebook and Microsoft aren't.

If you're going to include both, it would be nice if there were a way to distinguish and filter between these two categories. I really like the idea of being able to see all the open source jobs out there, but having Netflix at the top of the list makes me unsure how many of these companies are truly open-source-first.
