Might be to take the heat off them a bit with the Freeview stuff going out, wouldn't want to slow down the initial sales with a forum full of complaints...
There is always DTV Forums & Whirlpool for that

The sad thing is (like Mike mentioned above) the current 7100 & 7000 has pretty much been stabilised and the forum had become very quiet after the last public release.
Even a few of the people with major problems had noticed their boxes suddenly become reliable.
Both my 7000 and 7100 are rock solid with the latest firmware since it was released in Mid March 2009.
No freezes, no missed timers both Ice & FTA, FTA EPG is fixed in my area and it's done everything I've thrown at them both.
But mine have always functioned very well and I've never had any major problems
