It is a problem - just more global. With PR moving into more and more orwellian grounds there should indeed be widespread public education on their practices and how to avoid/protect from them.

And with the crackdown on fake/paid/influenced reviews, shills and other similar stuff seems the society is waking up.

While I strongly condemn limiting the freedom of speech I do think that there should be detailed disclosures on what kind of stuff the person doing the review is getting. And yes early access should be on that list.

Transparency is a potent tool.
