I'm in web dev, not quite the front end guy I have to admit. Blocking a whole site it's more effective. full stop. site isn't working? not sure I'm losing anything. furthermore I can whitelist my localhost during dev allowing google/facebook/twitter/etc. stuff for example, and remove it anywhere else. add that I browse only in private. also as I said, i have ublock enabled side by side with noscript: I need to fine tune something? well I have my options, you know. so no, my opinion is not objectively wrong. it's just that we have radically different needs: you want to have the (most legitimate) chance to spend time filtering script by script, I need to be quick around things. It's my way better than yours? prolly not, but that vm helps me a lot. peace.
