Ad revenue is slowing going back up but people like Vegan Gains who stand up for an ideology, and VG stands for a lot more than Veganism, are penalized by Youtube.
Youtube's algorithms pick up controversial words and will demonetize certain videos. They did this before the big boycott VG is now complaining about. He was hit big weeks before he put out these videos asking for donations.
Once your video is demonetized, it no longer has ads. That takes away your incentive for creating similar videos because you'd be working for days on a video and not get paid.
Then you don't even want to stand for or say anything controversial because you won't have any ads and won't earn an income.
Bigger, smarter companies like Info Wars sell their own products. Their videos are their own commercials, so it doesn't matter nearly as much if they are monetized or not with Google ads.
This hits both the independent left and the right. If you're snickering and giggling because you think the right is hit more, it hits the little-guy left just as much as the little-guy right.
The big mainstream corporations like Fox, CNN, etc... are not hurt at all...which should make many on here happy because you only want to consume info created by big companies and hate people like yourselves.
