Tesla did not rank worse. The article could not find anything bad to say about Tesla's actual practices, so they scrounged some stuff up like "having AI means Tesla bad" and put in the Tesla statement that removing connectivity stops your ability to get software updates — well, yeah... They neglected to mention that any data Tesla collects does not identify you — even better than that, it does not even identify the specific vehicle. They do have the ability to go back and forensically get data for a specific car in special situations (accidents needing investigation for example) but they are so far ahead in privacy it's a joke that the article tried to portray it otherwise.
