I've been on teams where the "siloed" QA model seemed to work pretty well -- we seemed to find a decent balance between test coverage and frequency of releases.

But this was at a cash-rich startup that had lots of money to spend on making sure we had plenty of QA headcount. That seems to be the exception, rather than the rule. Lots of startups I talk to are quite constrained in terms of dedicated QA, so the argument for empowering product managers to own quality does make some sense to me.
