Because they have kernel developers, qa, and other staff dedicated to
making that kpatch work? They have a large set of servers to test
different workloads? They have some time before the kernel is built
internally and when it is made available externally to do all this and
hand tune any problems found? Because big companies are paying a large
amount of money to make it work and so the extra labour is profitable?

In the past, all of this would be a challenge for people to come
together and show that they can also do it themselves... or improve on
something to make it so less labour intensive at parts. If that
happens, I am happy to have laid out the challenge :).
