That doesn't sound accurate. Anecdata, but in my current org in Amazon Retail I think about 1 in 15 engineers browse HN daily. When I was in AWS it was around 1 in 3.

Why do you think people in Google/Netflix/Facebook browse HN more than Amazon/Apple?

Historical trends on similar threads. Other "Ask FAAMNG" threads seem to have a disproportionate number of responses from Googlers.
