uBlock origin has a lot of features beyond being a simple ad domain blacklist. You can remove elements from websites at wish. It can spoof information about which fonts you have installed to websites, block WebRTC and more. A pure ad blocker with a smaller feature scope will require fewer permissions. While I have not read the source code my self I have a hard time believing that uBlock origin is not limited to the lowest amount possible of required permissions to do the job it does.
