And why so many osquery team member left facebook after they work on osquery just 1~2 years. such as @javuto https://www.linkedin.com/in/javiermarcosdeprado/

Uh, that’s not really what I’ve seen.

Given that you have taken an interest in my trajectory, when I left Facebook (although I still contributed to osquery after that, but not as much) I had been there for over 4 years (fully vested) and found a good opportunity elsewhere. I don’t understand what is your point, but let me know if that clarifies it!
