Increased demand never limits growth. That would be a retarded position to settle for when running a business. A company that sees that it's reaching the limits of its present infrastructure will not just sit on its laurels and say that they can't deliver to the customer. They either will have to expand or face losing customers to someone who can deliver.
This reeks of an industry advertising campaign for Akamai, Limelight and other content providers masked as loose "research".
Technically they could "say" that we will run out of bandwidth, but that will never happen.
