It is more or less ease to change kernel behavior since:
- kernel is available
- there are good tools to do so; and good documentation
- nevertheless, it has a complicated structure so it has to be done by a skillful person
But even if someone change OS kernel to compromise DRM structure, he has to deal with the problem for replicated and disseminate.
So he has tow options:
- a source patch to kernel is disseminated to other users, but then the patch depends on the kernel versions and it makes necessary to recompile the kernel OR
- the entire kernel is distributed but that is a difficult task because implies to distribute a large number of files that are very related wit the hardware components, which implies a later configuration
... so, although it is could be a thread, there are some hard issues to deal
