You're taking advantage of content that was paid for with the attention of people besides yourself. This is no different than grazing on a green you don't maintain.
If you're so opposed to ads, don't read content. Don't pretend that anybody is forcing you to visit ad supported content.
At the very least, you should know by now that most major websites depend on advertising revenue. So I assume you won't click on any of them. I also assume you never use Google or Facebook.
If they can't get people to pay for their content, maybe they should consider a line of work they can monetize without subjecting every single transaction to third-party skimming and engendering massive surveillance projects.
I'm entitled to survive off the art I'm creating after all. Everyone should be paying me for making art. Regardless if it is of good or poor quality. I made it - thus people should be paying me!
Does that argument sound absurd to you? It should.
If people aren't willing to pay you for your art (or "journalism" as is often the case) then guess what? You aren't entitled to their money. Stop making art/journalism and find a better career. If people really value your journalism (or simply "journalism at all") they'll pay for it to be around.
If nobody is paying - nobody gives a shit. Content creators don't get some free pass to do as they want and expect to get paid for it. If they aren't producing work worth paying for - guess what? That's their problem not anyone else's problem.
E:
Figurative third person use of "your" and "you", for clarification of the usage.
If your business model fails without ads, I'd suggest you have no business model at all.
