When I read this,

extrait : "YouTube is currently running what it describes as a "small experiment globally," warning users to toggle off their ad blockers and avoid being limited to only three video views."

I wonder what wrong must have happened for youtube to be so anal.

Guess what, youtube is now against ad blockers.

Probably everyone saw it coming. First of all, youtube introduced non-stoppable ads and annoyed pretty much every human on the planet with it. I guess ad blockers must have moved to find the filtering rules needed to block those non-stoppable ads, even though I don't see this in practice yet. Youtube must know adblockers made a move, and youtube is now reacting to this move by making sure every fucking user either whitelists youtube or creates a youtube account only to watch videos (just as doomed as twitter asking for an account only to watch tweets).

In the end this is not going to end well for youtube. It's way too hostile.
