I understand that position. But that's a losing position. It's an arms race, ad-blockers will always find clever ways to bypass these schemes then consultants will come with more complicated scripts that will make web pages heavier and harder to visit for those who don't block ads ...

The Washington Post certainly is not going to win that war. The only solution for them on the long run is all their website behind a paywall, like the Financial Times.

I'm curious if youtube is going to do the same, since they introduced an ad free paid offer.
