This is a strong accusation. Which of those brands are recommended by the FSF [0]? Which of them are actually trying to change the industry with their investments (promoting freedom/privacy) [1]? Which of them are fighting against planned obsolescence by providing lifetime updates [2]? Given all that I am not sure who is a hypocrite.
