I used the mass / weight as a pisstake, but as you ask..

A manufacturer of vibration motors rates the force output in Kg of force (KgF) as it makes g calculations (feed at 4 g, screen at 5g etc) easier.

Another manufacturer insists on Newtons, rating their motors in KN. Being technically correct.

Having been involved with both, many years ago, I can be comfortable either way as neither sell their products other than on the earth, where there are 9.8N of force to a Kg of mass in potential. So I don't get wound up by such things.

Mrs Musket, a surgeon, was subjected to a pedantic answer by a patient a while ago when asking the patient how much they weighed.... When she related that odd comment, it reminded me of the "that isn't folk" bores who think folk clubs are a pedant society for librarians.

Terribulus. If they are marketed as folk and people buy them because they associate their tastes as folk, they are folk as far as they are concerned. If you see folk as something different, fine. They are both folk. Saying something isn't what it plainly is puts your credibility at the level of the old fool saying if it can be copyrighted it isn't folk...
