Well, I have 40+ years of photography behind me and every once and awhile a product can develop a glitch just from regular wear and tear. No dropping required.

Eventually the dials on todays cameras will stop working like my T-90 from 1986, after 10 to 15 years. The graphite spray brings them right back. The problem is no one uses a digital camera for more than 10 years so they will never come across this issue.

My metal screw on lens cap for my 40 year old fisheye started binding a couple of years ago. Graphite spray fixed it immediately.

My 13 year old TS-E lens, that is my main lens, and with which I do a heck of a lot of shifting/stitching started binding a few years back, and again the graphite spray solved the problem. Especially in -20 C temperatures.

Yes, it is odd for the pin in a relatively new 1.4x III to bind, but one never knows. Canon is not perfect. I could see the pin getting damaged in a high use, and perhaps somewhat abusive use.

Keep your cameras and lenses for a long enough and you may find a use for graphite spray.

yes, that is called "Entropy" in physics (2nd law of thermodynamics) nothing can escape from it.
