I recently canceled my Amazon prime subscription after having it for almost a decade. The final straw was Amazon removing the ability to comment on reviews. First, they remove the ability to see the comments using the mobile site, then they remove them all together saying that not as many people were utilizing it. Unfortunately, those comments were a good litmus test to the authenticity of a review - positive or negative - and gave insight to the responsiveness of the seller. Some comments on reviews even had instructions on how to solve the reviewer's problem from experts in the field, it’s all lost now.
