I fucking hate that coating. It’s the bane of electronics casings.
I hope it’s never used again, but I still keep seeing it, especially on third party game controllers.
If it’s a rubberized coating on new devices, it may be a similar formula that doesn’t have the degradation problem. I haven’t personally had any devices do that in several years (not saying that there aren’t products that do, mind).
And I remember that when the coating was new, before it broke down into a horrible sticky mess in a few years after purchase, it did feel pretty good to me. And it seemed pretty durable – like, it didn’t wear through or anything.
Just that when the Stickyocalypse did happen, it was awful.
I remember reading on Reddit once that people who bought a variety of dress shoes with a particular type of substance used in their soft soles had something similar happen. For a few years, many types of shoes from different manufacturers would break down and degrade in the closet. You take them out after a couple years, and they just crumbled apart. Wasn’t a sticky mess, but I bet that people who rarely wore those shoes were pretty irked.

Here’s an example of one manufacturer that sold affected shoes. Apparently the problem was polyurethane being affected by hydrolysis.
Anyway, point is, the industry moved away from that particular fiasco after a couple of years when the problem came to light, switched to similar substances without the problem. I wouldn’t be surprised if the electronics industry has done the same.
