Stylus friction as a cause of static charge on LPs

The advertising blurb on the website posits that friction of the stylus tip in the groove is one cause of static charge build-up. The idea seems plausible to me, so I don't dismiss it out of hand. But in the only "scientific" study of static charge on LP surfaces that I know about, published in a white paper by Shure Corporation probably more than 50 years ago, the Shure investigators said they looked for evidence that stylus friction causes static charge and found no good case for it. Unfortunately, while the paper describes in detail many of the experiments they performed in order to characterize static charge on LPs, it does not describe the particular experiment they may have done to rule out stylus friction as a cause; they just say results were negative.

It may be that the idea is just one of those ideas that has been repeated and re-repeated so often it has become "true".
