I understand that the vast majority of reviewers on the internet, and certainly the sites that come up first in search engine results, are compensated by the manufacturers via kickbacks.
Is there any good work being done on solving this problem? "Verified buyer" exists on larger sites but it doesn't solve for kickbacks. Looking only at reviews written by people closer to you socially also doesn't work since at that critical proximity there aren't enough reviews.
Builtin ads or DRM should be a major point in any review or feature comparison matrix.
