no, this is somewhat good news. IE was going to stick around for a long time anyways, because its the default windows browser and there will always be people who don't know better than to use the default.

this will just hasten the migration away. its probably not a huge win for anyone with respect to directly converting it into migrations to another browser, because the people who were clueless about switching probably still will be.

its just a really nice selling point when you have the ear of someone, trying to convert them.
