the privacy grading is a cool idea and i'd love to have that displayed in my address bar for every site i visit, but bundling it with a "tracker blocker" means that the extension needs full access to all my data on every webpage i visit. i think my privacy is better protected by having one fewer extension installed with such broad permissions.
A good tracker should only be running locally. Ublock origin is just local rules and filters, nothing is being logged or sent anywhere. I'm not sure about this one, however.
