Reading the full thing he's clearly saying:
PSN
Pros - developers allowed freedom to determine online service provided
Cons - requires more developer effort to build up what they want to deliver
Live
Pros - more developed infrastructure and toolset
Cons - more restrictive on developers on what they can offer
He doesn't seem to be talking from a user perspective at all but a developer one, and from what I understand of each his comments sound pretty accurate to me.
Try to be reasonable... its easier than you think...
