Not the best article. It basically entirely ignores how this is going to hurt the small/indie developers the most, who are the main reason Unity exists as it does today. Indie games will have lower price points than AAA games, and thus Unity's cut is a larger piece of the ever-shrinking pie. My personal opinion about this whole fiasco is that they'll go back on their original statement to something still quite greedy…
This will turn off new development, though.
