I don't think that you have any reason to feel disappointed, unless you have donated a significant amount of money to Adblock Plus. And even then, just disable that feature.
After all that's the way Adblock Plus makes most of its money, needed to develop the browser extension, port it to new platforms, maintaining and hosting the filter lists (which by the way are also used by every other ad blocker). I doubt that if Adblock Plus wouldn't have done this step, it would have ever been ported to other browsers and platforms, and that the filter lists (as mentioned, also used by other ad blockers, like AdBlock), would have been that well curated as of today.
So I don't see anything wrong with that. Or does anybody complain, that most free Android apps show adds, and you have to buy the paid version, to get rid of them? No, everybody understands that this is the way they make money. The only difference in case of Adblock Plus is, that you don't actually have to give them money, but just have to disable a checkbox in the options.
By disabling that feature, he would block all ads. However, he did say that he wants to support sites who rely on ad revenue. I don't think supporting Adblock Plus was what he was really concerned about.
I might got his message slightly wrong. However white listing is is a feature in the filter list format itself, that is used ever since by every ad blocker. So you can include third-party white lists or maintain your own with every ad blocker, already before Adblock Plus introduced "Acceptable Ads" and its own white list.
The important point for me is that one of the major adblockers has enabled a whitelist by default, and is curating it to allow non-intrusive adverts. That can affect enough users to make a difference, which my setting up a whitelist myself wouldn't.
