uBlock Origin and any other effective content blocker had that as its most important weapon, without exaggeration. it has many other techniques for specific circumstances, but preventing to load the ad scripts, and preventing network requests that send back data to the advertising company, are universally a powerful tool.
You're just repeating what you already said.
My question is: since there are (and always have been) other privacy-oriented extensions (e.g. Privacy Badger, Ghostery) and they still work just as they always have, what is the advantage of specifically using uBO with Mv2?
you don’t see them because addons can still insert unlimited cosmetic tweaks. CSS snippets that make specific elements hidden. but the ads are still loaded, consuming network and CPU resources, and the ad framework still collects usage, interaction and device data.
I just loaded up YouTube and didn't see a single call to a known ad server, so this seems to be false.
Also: the CPU usage of loading even a couple MB-worth of ads is negligible compared to the overall resource hungriness of Chromium.
(...) list updates are released much less frequently (...)
I did notice that every now and again YouTube would block me from using it due to detecting the adblocker, but is that an inherent disadvantage of Mv3? And why wouldn't the extension developers then embed the updated filter lists and just release them as extension updates? Does Google limit the frequency of those?
