Scary, isn't it?

One of the problems is that corporate lawyers require the full GPL
preample in any source file. As a result, a lot of developers inside
companies cannot publish code without it. Whether that makes any sense
is anyone's guess. But it doesn't cause much harm either, so better
leave the bloat where it is.

It may be 3.5 MB uncompressed, but disk space is cheap, and repeated
strings compress extremely well to save bandwidth. If you work with the
kernel source enough for this to be an issue, you should use git.
You'll download these license headers once, and never again unless the
copyright info gets changed by a patch. From a technical perspective,
the problem isn't nearly as bad as it looks, and it keeps the lawyers
happy, so it's really not worth messing with. There's plenty of
lower-hanging fruit in unifying drivers for similar hardware, unifying
32-bit and 64-bit architectures, and other things that make the code
more maintainable.
