I wear those gloves when working with oil or chemicals, at least when I'm home and have a box of gloves handy. In high school my auto shop class teacher had skin cancer and didn't wonder how he got it, gloves were a requirement for the class when we were wrenching, either rubber gloves or mechanics gloves depending on the situation.
As for trends in motorcycling, what manufacturers are doing and what "influencers" and content creators are doing have overlap and relation, but keep in mind what you see online is not a proportional representation of riders.
