Most people don't care. And that's fine, they don't have a reason to. There's a lot of other things that are probably a higher priority for them.
Bigger question is if you're going to be doing things that are in any way considered shady or bad, why would you not take any precautions?
This is why many/most reviews are actually useless.
Many people use reviews to complain, about anything, especially if it has nothing to do with the product because it's the easiest way to try and get it out of their system.
Combined with fake reviews, astroturfed reviews from undisclosed free products, and the average user having no knowledge of a product or category to compare against, etc. and I'd even say most reviews are effectively useless.
On the bright side, seeing any of those types of phrases in the review means you can effectively ignore that review entirely.
