Microsoft's unpaid testers

I just discovered this charming little quote in the winows 7 blog:

To date, with the wide usage of the Windows 7 Beta we have received a hundreds [sic] of Connect (the MSDN/Technet enrolled beta customers) bug reports and have fixes in the pipeline for the highest percentage of those reported bugs than in any previous Windows development cycle.

So you're publically advertising the fact that your product was very buggy when you launched the beta test phase, and you're scrambling to fix all the bugs at the last minute? Whatever happened to internal testing? Who will test all the bugs introduced with your bug fixes?

Bah, my dislike of the Microsoft software mill continues! Hooray for uninformed opinion!
