One of the jobs of the Linux kernel—and all operating system kernels—is to manage the resources available to the system. When those resources get used up, what should it do? If the resource is RAM, there's not much choice. It's not feasible to take over the behavior of any piece of user software, understand what that software does, and make it more memory-efficient. Instead, the kernel has very little choice but to try to identify the software that is most responsible for using up the system's RAM and kill that process.

Linux definitely gives users more flexibility and granular controls over its file systems' security permissions. This may imply that it's critical for Linux users to understand security permissions. That isn't necessarily true, but it's still wise for beginning users to understand the basics of Linux permissions.
