Doubt it's that. They have a normal amount of real estate for a software company. From what I've seen of their culture (at least some parts) it's just more relaxed. Maybe not in cloud but in other areas. They also seem to go in less for other top-down imposed cultural trends like DIE.
I never went to one of their offices. Probably boring office park vibes. Unlike the space donut and amusement parks it sounds like Apple and Google workers require to crank leetcode
Offices are ok, but nothing like FAANG (I've never been to Netflix's hq, but am guessing). Cafeteria food wasn't free either, though was pretty cheap.
