Unless they are referring to paid advertisements by the creators.
The creators would presumably take a cut/fee from YouTube for showing their content ad-free. sponsorblock already does something similar.
Creators already get paid very well for posting on YouTube.
A good rule of thumb for me is, if I see adverts on YouTube and on TV for the same company or product, then they are charging too much..
I choose to avoid them.
if somebody is advertising a small company/startup etc..
Go for it.
But if a creator has ads on premium that costs x amount each month.
Nahh...
