It would be super convenient to install the application with a simple command like brew install --cask wBlock (I'm pretty sure that Homebrew will accept PR to homebrew-core easily)
Or start by preparing cask and all can add 3rd party repo and install brew tap 0xCUB3/wBlock && brew install --cask wBlock
