The problem here isn't the "brandjacking", it's the "curate this page" option. As a customer, this sort of site is only useful if it's uncensored and focused - I want to read about the Kindle DRM problems along side the fawning reviews.

Basically, "curated" pages become useless. Non-curated pages might be useful, but I'm not going to trust a site whose business model depends on "pay us to take down negative reviews."

This isn't an ethical issue, it's just a big gaping hole in the business model.
