Not sure about that analogy haha... But, I admit some of this comes from my frustration when thinking for a second that the post I'm looking at is from someone I'm friends with or follow.
From my experience, adblockers are meant for ads specifically, not promoted or sponsored posts that seem like native content. I've seen some chrome extensions for site specific sponsored content (like facebook), but the one's that I've tried are inconsistent. Which is why I made this :)
