In a business where you can cash in several times the cost of an employee in profits and where some hires are literally 10x as compared to the average engineer, it makes absolutely no sense not to try to get the best.
With remote, that just means they can get the best and brightest from anywhere in the world to apply there first.
Sure, they won't hire the ones who are there and not willing to move out but that's probably a small pool compared to the rest of the world.
