Because it isn't always possible to update to the latest and greatest. Besides, a fair amount of the compatibility issues I have run into have fairly simple one-time fixes. True, there are some things that can't be patched and over time there will be no choice but to drop support for the older browsers. However, there is quite a bit that could still work on older browsers if only the devs cared just a bit.
