The concern most designers have is with crowd sourced spec work such as 99 designs which is a threat to a lot of freelance designers.
That said, I really don't see where the problem is in the design ecosystem right now. Talented designers are not having problems finding really well paying work, in fact there are probably more opportunities than there are designers. On the other end you have the 99 designs space. Here there are a few hundred "designers" rehashing the same concepts, over and over, for clients you'd NEVER want to work for on anything significant.
You pay for what you get.
Crowd-sourced spec work is another matter altogether. If a potential client points to those sites as a way of driving down your price, they're not the kind of clients you want to work with.
There's nothing wrong with taking on a high profile job for the exposure and doing it for free if you treat it like an extraneous circumstance and a business decision. But compared to people in other fields, designers are a little soft on what are acceptable payment terms, and are often taken advantage of as a result. Free = free and paid = paid, but "spec work" is a grey area that is on the whole bad for the community.
I think a lot of people are taking people's anti-spec to be very black and white, especially from the email and private communication i've received from this. :)
