CNET doesn't seem to have the greatest track record with editorial independence. Wasn't there a big blowup at gamespot a few years ago too?
GameSpot terminated their Editorial Director after giving a game a less-than-glowing review. However, this occurred before CBS purchased CNET.
Gerstmann and GameSpot's John Davidson spoke quite candidly about the acquisition [2] at the time, including the thorny issue of Gerstman's previous departure from GameSpot. Makes for an interesting watch if you remember when the original scandal broke over the original Kane & Lynch review.
