Stupid fucks like you piss me off beyond sensible limits. You are putting questions in there that were not ever there.
I explained. John invented the JJ. Then when its success was noted, others started knocking it off with cheaper versions. In order to compete against bullshit copies that are not as good, not the same and whole only value is a lower price point, John deleted the greaseable bolts as standard in order to reduce the selling price. In self defense, they added a grease fitting because the omission of same would cause far more bullshit than one that isn't exactly as useful as it should be. Like it or not, believe it or not, that is the way it happened and your insistence on being a little shit won't change that.
