Is the difference that Apple product launches are (not exclusively) intended for consumers whereas the Wall is aimed almost exclusively at large business's lobbies?
... and for luxury living. Luxury car launches are covered on the hn frontpage as well, e.g. that weird car whose windows Elon broke... probably increasing its value in the process.
What's "wrong" about this? No one has provided any evidence of manipulation other than speculation. Maybe people are interested in Samsung's display technology?
I don't know how to provide evidence of manipulation as an outside observer. I was pointing out that it does seem strange. But maybe this is the course of HN nowadays.
