It absolutely is our job as engineers to change the world. We're the experts. We've done the research and have the evidence to support our positions. From there it's our duty to show the rest of the world the best solution for the problem. In this case I think the problem is number of developer cycles that go into IE compatibility. Imagine if all that time went to the actual product.

Often rubbing something in someone's face is the only way to evoke change. To degrade the experience and let the user know why it's been degraded gives them a clearer understanding of the problem. Being struck with the same problem enough times tends to get someone to act to solve it.
