Re: "We’ll strike back," he promised.
What can the ad-blockers Facebook do that can't be easily undone by Facebook the ad-blockers?
Is more to the point. Unless FB runs adverts from their own servers just like user posts, its still easily separable. And if they do that they can't rely upon 3rd party advertisement houses for revenue.
That is, of course, quite possible. But then the second step is for ad-blockers to disable any animated image/video by default. So FB still punts ads, but they are now neutered in terms of bandwidth and annoyance so really the user has won by not being force-fed any more shit that their "friends" on FB normally punt at them.
