After over a week of trying to get a meeting with @TeamYouTube we finally have one scheduled for an hour from now. If you have any constructive feedback to share with them regarding the abbreviated subscriber numbers (via the api), reply to this tweet.
If they want to bring consisitency, they can do this change, but make it like the 'like' count, where hovering over the line will show the full number of likes and dislikes, and the api should have the full live count still available
