Given Uber is one of the few companies who are lucky enough to have a separate page for all the controversies on Wikipedia (https://en.wikipedia.org/wiki/Controversies_surrounding_Uber), they also have their own fair of experience with police raids on their offices. They've also used "‘kill switch’ during raids to stop police seeing data" (https://www.theguardian.com/news/2022/jul/10/uber-files-leak...) before, so I wouldn't be surprised if this was some sort of legal "kill switch" or whatever that got triggered, so they can get rid of everything faster.
