Recently, there was a post on reddit where people posted the amount of money content creators are getting from views with ads.

I don’t remember the numbers well enough to quote it but it’s barely anything. I recommend to look it up.

And the biggest surprise for me was that older videos get even less.

The money can also vary a lot depending on what advertisers are trying to advertise on your account. Dan Olsen talks about there being a minor bidding war for his Line Goes Up video because it was attracting crypto advertisers during a frenzy so they were bidding up placement on anything related to crypto.

The money isn't great by itself but it's still money coming in too.

It could be because people are blocking too many ads?

Just so the lede isn’t buried: a creator in this sense creates content for money.
