I agree with Easter Eggs in products. That being said another good example of an "Easter Egg gone wrong" was the games in Excel 95 and 97. Excel 95 had a "Doom"-like 3D game. Excel 97 had a basic flight simulator. These were fun and weren't buggy, but here's the problem: How much time do you think was lost in classrooms in particular after all the kids discovered there were games they could be playing instead of work…
Perhaps it is not microsofts responsibility to ensure kids are always hard at work.
However it is unfortunate that they decided to conflate a product needed in a classroom (namely the Office suite) and a feature which is not (namely a game).
Microsoft's only responsibility is that their software is fit for purpose, and in this scenario it is not.
