"That Bastion of Socialist Game Design"

SPI is well known for its publication of the famed wargames magazine Strategy & Tactics, but the company also published a second periodical, Moves, which first appeared in 1972. Whereas S&T was a more general wargames magazine, Moves focused on the play and design of specific games, providing play reports, variants, new scenarios, and reviews. 

Recently, I was reading issue #35 of Moves (October/November 1977) and came across an article entitled "Captain Video Returns." The article is a collection of brief reviews of science fiction games, both wargames and RPGs, the author, Phil Kosnett, came across at Origins 1977, held that year in New York. Among the reviews is a glowing one of GDW's Traveller. I reproduce the entirety of the review below for the benefit of readers. Take note of its first sentence.

I assume – without proof, mind you – that calling GDW "that bastion of socialist game design" is a joke, a bit of gentle ribbing at GDW's expense, but perhaps there's more to the comment than I know. If anyone can shed some light on this matter, I'd be appreciative.
