I doubt few would argue that gaming is a passive activity. What they seem to argue is that any gaming experience specifically designed for entertainment is ultimately worthless.

There’s games all around us if you look. I like to play the “I broke my kernel and my entire system is fucked and now I gotta repair it” game or the “write a driver for some obscure hardware” game or even “demonstrate a vulnerability exploit on a live system” game, all which lead to greater value creation and self fulfillment superior to defeating some imaginary creature.
