Here is an Odysee Link for those that don't want to give youtube support.

Just a PSA for those who don’t know… no shade against Odysee… I’ve just encountered folks here who don’t know this:

Veritassium and many others on YouTube make their living by the advertising shown on YT. If you’re a premium member, even more money goes to the creator when you watch their content. It’s this very money that allows independent creators to create more / better content!

So they get more from the subscription fee without ads than they from the ad revenue? Many also have their own sponsors, right?

Yes to both!
