Seems a narrow and overly commercial view - but maybe that's his only angle.
They get a ton of support, they seem to be profitable and it's pretty clear they are a great place to work and have a lot of fun with what they develop.
They also have simplified development environment (although to be fair I doubt it would add that much cost to add 360 development skills and ability).
Not all companies focus on profit - if so then technically there would be no exclusives. For example if Insomniac are nuts not going multi then you'd argue Remedy are with Alan Wake where they're probably missing a fair amount of sales on PS3.
Some prefer focus and strong partnerships and that's fair enough I guess whichever company or console they chose to focus on.
Try to be reasonable... its easier than you think...
