Earlier quoted context omitted.
Not to take away from the people who worked hard to shift the culture (which is always hard at a large company), but I saw the same shift happen at Amazon and it came down to a simple fact - it's very hard to recruit and keep the best talent if you don't publish. You don't build ML reputation and the best researchers often don't want to work somewhere where they can't add papers to their resume.
Not sure about this: a lot of interesting work is just hidden because of NDAs, commercial IP, military, etc. You will never see anything made public until necessary and just the minimum amount required.
It actually became really important to me over the last 5-10 years. I have no desire to discuss the secret sauce but I've been at companies so secretive that we couldn't even send a github issue up on our personal accounts because some context might bubble up eventually as to what we built and who we are.
I am so, so much happier working on my niche at places where I can interact openly with people from other companies/projects, not in a competitive manner but as engineering peers working to improve some subsystem of our architecture.
I feel like the shift is coming, especially with all of the open standards groups companies are rallying behind. I'm loving that. It's just taking its time to come east of SV.
