Current events aside, kinda insane how a Youtube channel with 6.6 million subscribers can get less than 500k views on a month old video
Basically in the default view I'm not sure it even makes much difference whether you're actually subscribed to a given channel or not; it seems like it's more about whether or not you've viewed the channel's videos recently.
It basically just means that the average subscriber is watching ~2 of his videos a month.
