Cons
Con Uses too much RAM
AdBlock+ tends to use a lot of memory, which has been documented in many use cases as well as admitted by AdBlock themselves. Considering there are alternatives out there that can block ads successfully with half the RAM usage as AdBlock, one has to wonder why this is a problem specific to AdBock.
Con Users automatically opted in to whitelist
AdBlock+ has an automatic whitelist when installed that allows certain advertisers through the blocking mechanism. The fact that these advertisers pay for this privilege makes this particular scenario rife with conflict of interest.
Con Acceptable ads turn on by default
Acceptable ads is an ad that follow the guidelines of the set acceptable advertising rules such as ads must be labelled "ads", no pop-outs allowed, no auto-plays, no animations, does not block main content etc. However, users can turn off this feature by going to settings and then unchecking "allow acceptable ads".
