Pros
Pro Works without asking for more access rights, your privacy is always respected
Pro Free & open source
Pro Blocks a wide selection of annoying ads
Video ads on YouTube, Facebook ads, flashy banners, pop-ups, pop-unders and much more.
Cons
Con Need an adblocking DNS server - not TLS and no DOH
You may use the odd guard DNS servers. But it is not very fair to use add guard servers without paying a little bit of money for the infrastructure. You may set up an own DNS server and pay for VPS server and traffic - thats fair.
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.
