Yes I know.. but they're also entitled to make spurious claims and even state outright lies in those reviews too because nothing is ever checked and there's no oversight. Those lies can also stay on the Internet in perpetuity in the name of "freedom of speech" and it's all done because the wrong sort of people say it's their legitimate and heartfelt opinion. These people hurt democracy, they hurt the Internet, they hurt freedom of speech and they hurt all of the rest of us in the process. If anybody doesn't think that's worth challenging, they can go and talk to someone else.
