YouTube costs about 1 billion to run per year at the moment and while it does make 5x that in income through ads and premium, I highly doubt it would have gotten to that level without the considerable integration with Google and the bias Google has to force users to YouTube results.
It's not an accurate representation of what video platforms can achieve, they are actively growing their TV subscription, music subscription and ad-free subscription to compensate for the ad revenues. They also have also ramped up adserving on videos to an unwatchable degree and I've had to use brave to block that garbage.
Since HIVE doesn't have 1 front end an ad revenue model is harder to implement as sites compete with one another for clicks. I don't mind the 7 day period because that's only their to push out the new inflation, what HIVE hasn't cracked is the secondary market where the inflation that's already out there is re-used to create more content and value.
LEO is trying to push it with its ad burning, posting tax and buy back from exchange fees and burn and I think more initiatives like that need to be tried and see what eventually sticks, or if its a combinations of things
