What people doesn't know is that uBlock makes use of EasyList as one of its default block lists. EasyList is maintained by ABP's parent company. That list itself has built-in whitelist that could not be turn off without revamping the list itself. That list contains upward of 60k of rules and no one has time to evaluate that for free.
uBlock can make all kind of independence claims it wants, but at the end of the day, uBlock is still relying on ABP for its blocking rules--which is no guarantee at all.
edit: lol why are people downvoting me for pointing out that uBlock is relying on ABP? uBlock never acctually claimed to not having acceptable ads. By using ABP's EasyList, they could already be running an "acceptable ads" whitelist.
edit 2: Here's the link to easylist for anyone that care to check out the included whitelist: https://easylist-downloads.adblockplus.org/easylist.txt
Warning, the list is over 1mb.
