The article strongly implies that widespread 300GB usage would not strain providers' capacity. As a consumer, I would certainly like it to be true. Is it?
Yes, for ground-based networks the capacity limitations are largely a question of expanding capacity at interchanges rather than any kind of actual network capacity.
If you are asking 'bout wireless....no, that isn't true.
For instance, TWC is quite profitable in my market with no cap and I've got a 100mbps in real-world usage most of the time.
Sort of, the capacity of fibers growth faster than the Internet usage. (But of course carriers need to upgrade their routers regularly.) Additionally most of the cost of ISP's is fixed cost, to build capacity, not variable with the total amount of data transferred. It makes sense to have a flat rate.
