Will Microsoft Open Source Internet Explorer?

I think Betteridge's law of headlines applies here. MS open-sourcing such a massive project which would be highly scrutinized publicly, there's bound to be some very ugly code in there. I don't think there's much to gain given existing open-source browsers being much further ahead than IE.

I think that is a backward thinking argument. We need browser competition. It doesn't matter who it comes from. The more browser choice we have the better.
