I always thought the antitrust ruling against Microsoft was a bit heavy-handed (and I say this as a former Mozilla employee). Like, it was the 90s... most people wouldn't know how to download and install a browser in the first place, so bundling (much like how iOS comes with Safari) seems fair.
But then they do shitty stuff like this, and it's a reminder of how overly anti-competitive Microsoft really can be. It's one thing to bundle, and it's another to make it so hard to switch that people finally just give in.
