        Can you make and test the kernel patches yourself from upstream fixes? Because that's what you must pay for (also for RedHat and SUSE). The kernel patching infrastructure is open and you can use it fine just as you can use Kpatch on RHEL or derivatives or whatever is called Suse's for SUSE or derivatives.

          While the patches are open source, Canonical's livepatch-client is not (source: the FAQ in the blog post that was the source for that article, http://blog.dustinkirkland.com/2016/...livepatch.html ). While that isn't ideal, it's at least better from a security perspective than running proprietary software from another company, since "Canoncial turns evil and starts secretly doing bad things to your Ubuntu install" isn't the most appropriate of threat models --- they control the repos you use regardless.
