* HQ being in Paris creates great challenges, while everyone on the Paris side is super helpful, the time difference just does not work. Most infra is in Paris and you could find yourself stuck until the next day, which is not the fault of the Paris folks, just a time difference thing.
* HQ being in Paris makes the promotion process non-transparent, people who put their head down and work hard can be overlooked for people who are buddies and hang out outside of work hours.
* Some of the code that Palo Alto and Ann Arbor teams work on; does not belong to 2019.
