If they please they can easily make content premium only instead of relying on people's willingness to see ads. If people can with a few clicks see no ads then 10-25% of people will probably do so while the majority continue to watch ads. Content isn't premium only because they have already run the numbers and they get more from the majority that watch the ads than they would by putting it behind a paywall.
