That was the USFS and I agree with their assessment! The rest of the story! A handle on a Pulaski (or shovel or axe) being used extensively on a fireline may last 4-5 years before the handle starts to splinter some or in fact breaks, unless it's a Forester packing a tool around in the back of their vehicle year after year, then a linseed coating may help prolong the life of the handle, otherwise linseed isn't justified for a handle that may only last a few years.

Hope this helps with the intent behind the discontinuation of linseed oil on the USFS tool handles (and the safety issue) and I would guess most State Forestry and Fire agencies as well.
