We're private citizens, nothing prevents us from criticizing them for a wide variety of reasons. If you want to restrict yourself and ignore everything except the literal function of the product, you're free to do that, but you can't argue everyone else has to do the same.

Or is your argument that we have some kind of social responsibility to judge products based on exclusively on what the product does, but the product has no social responsibility whatsoever? That's a double standard that can't have any justification.
