A question was: What good comes from it ?
I'm pretty sure I didn't say a single thing about anything good coming from it...or that it was beneficial and should be done, etc.
I simply took exception to the arbitrary claim that was made, and introduced actual facts into the discussion, commenting that I keep an oily rage in a big ziploc bag on the workbrench at all times, and whenever I'm done working on / handling a gun, I use the rag to wipe down the enire firearm.
It would be a needless waste of my time to slow down and painstakingly very selectively wipe down only the metal parts scattered here and there, when no harm comes from the oily rag also contacting the stock in the first place.
So to reiterate, I've used nothing but an oil/WD40 based cloth to wipe down every Ruger, S&W, Remington, Marlin, Thompson Center, and TVM built guns I've owned since the '60s...easily well over 100+ rifles, shotguns, handguns, muzzleloaders...cheap hard wood, cheap walnut, expensive walnut, expensive curly maple...never the first problem in a half century.
If there happened to have been an instance that some sort of damage occurred to one gun stock somewhere in the country, the root cause of that instance needs to be investigated to precisely identify the source of that problem, and not assume / indict an entire industry that oiling gunstocks causes problems.
And I believe transmission fluid is also recommended for wiping down gun stocks.
Anyhow, I have no interest in getting anyone to wipe down anything with anything...I was just correcting a claim using decades of actual hands-on, fact based experience.
