Owner maintenance of stuff that isn't legally so, it sounds like. That strut can pop right out with the link disconnected, and then what do you do? If you let the nose go down enough, the CG shifts forward enough that you might not be able to stop it, and you at least crumple the cowling, and maybe bend a prop blade. If the strut stays in the cylinder an inch or so, any weight put on it will cock it and destroy just about everything there.
