It wouldn't take much effort on Coinlab and Mtgox's part to have a blog where they could spend 3 minutes a day updating people about the situation..
They did post on another thread that they wanted to hire a PR person. I suspect that's because whatever Mtgox or CoinLab say will have a noticeable effect on the market.
So in one sense, they're being fair by not posting anything. If they did post something, someone would start to claim they were insider trading on the volatility they can cause.
Still I would personally rather see regular posts. It would be more fair if they posted exactly one article at exactly the same time each day (0:00 UTC maybe?).
