Edge has been passable, Edge gained users, someone at MS suggested they should exploit those users more -- 'they're enjoying it, we can make it shit and exploit them for money instead, go us' is how I imagine that thought went.
If MS stay true to form then give it a year and Edge will be a fetid turd, but they'll add some lock-in from the OS; maybe Office online breaks in all the other browsers. The World will be worse, some middle-manager will get a promotion, shareholders will get a few more cents, so it goes...
