Blitz has always been more centrally controled from WG Prime, all the events, specials and what not are identical through the four servers (with minor exceptions). Whereas on PC, many events, specials can be drastically different, even the update dates are different by a margin of a few weeks.
Then with the recent covfefe with the SirFoch/Chrysler K on PC incident, where EU created the mess, sorted out, only for NA to come in to screw it all up again due to the complete lack of communication between regions. Which resulted in losing at least 3 CC in the process, including Jingles, and frankly, this sort of stuff up can't be repeated.
The lack of communication between the regions have been an on going issues for ages, they probably decided enough is enough and since Blitz was more centrally organised to begin with, might as well go the whole way.
