I love this game so much. The video is very accurate but doesn't mention that once you overcome the hurdles this game throws at you, you can become so damn powerful that your wand can shoot 50 nukes per second that each erase the entire world you are in which temporarily reduces your framerate to several seconds per frame.
Yet you'll still die if you step into two pixels of the purple stuff and something shoots at you while you got turned into a flying sheep.
Steam didn't get to where it is because of market abuse but because of providing a good service, or at least a service that was better than anything else at the time by far. Valve are reaping the rewards now, but are also still providing an arguably better service than it's competitors. It's a bit odd that you want to punish a company just for being successful.
Valve isn't perfect and they're profit driven, but they're privately owned and the goals isn't maximizing profit, which isn't something you can say about most of their competitors.
