Why do some scope makers refuse to disclose their source of glass & who polishes it.
They must have some reasons I was wondering what those reasons might be.

The biggest reason is that the manufacturer of the glass is largely irrelevant to the vast majority of scope buyers. Who makes it is far less important than how it is specified and manufactured.
One of the (very) few glass manufacturer names that is readily recognized here makes everything from lenses for high-end scopes to simple flat panes of glass that are used for appliance fascias. I'm pretty damn sure that you could go to them, get lenses made that were roughly the same optical quality as the bottom of glass cookware, and then advertise that your fancy new scope uses Brand X glass. Would this having any meaning? Nope, none at all.

The lens coatings are AT LEAST as important as the glass itself.
Since there's only a few different plants around the world that make glass, most scope makers get their glass from the same plant.
