It is pretty clear that unlike these two we don't receive money from publishers.

Introduction. This list has nothing to do with «Acceptable Ads» program from Adblock Plus. We do not get paid by site owners. Ads listed here are not «acceptable», but useful to many users. At the moment, the list contains mostly search contextual ads (which are often more helpful than the search results) and self promo ads (promotion of the website’s own content). If you do not want to see these ads, just do not turn on «Filter for useful ads».
It is just misleading that AG is listed there as we have nothing to do with that section description. Taboola case is really shocking, and from the article it seems that we are related to this.
The list of 'acceptable' advertisers is always growing.
You've seen the list. It is very short and it is not growing. There are only self promo ads and seach contextual ads. Both types are obviously useful to users which is why that filter exists.
Self promo example: deals promotions on amazon.com. In general we are trying to not block such things (due to our policy: https://blog.adguard.com/en/adguard-news/adguard-filter-policy.html). But if it is blocked by some "wide" filter rule, we unblock it in useful ads filter.
