Isolated cookies is not 3rd party cookie blocking. Based on commentary I think google has done a good job of misleading people. ITP and isolated cookies are a response to companies like Google and Facebook developing mechanisms to defeat/undermine 3rd party cookie blocking. Google's "tracking protection" is something Safari did from the very first beta two decades ago, Firefox adopted 3rd party cookie blocking more recently, but that's all google is doing right now, and (presumably because) it's a tracking mechanism that they have already defeated. They're calling it "tracking protection" to try and launder the "tracking protection" terminology of actual privacy mechanisms and terminology of other browsers, rather than actually acknowledging that what they're doing now was insufficient years ago (when safari and firefox had to introduce a bunch of very complex logic to continue to actually protect user privacy).
