All public forums have an astroturfing problem including this one

Google, Apple, Microsoft, Amazon, Facebook, etc they all have hundreds of thousands employees and even if they are not explicitly paid to astroturf, they try to be subconsciously loyal to their employer, downvoting everything that goes against their subtle wiring, and happily upvoting every new product or feature launched by their org

That's just human nature, proven in 3, 2, 1...
