These types of articles are misleading since they interchange spectrum for capacity, which is not correct. I think the carriers allow this intentionally because of the way our FCC allocates spectrum and gives exclusive use to favored bidders. They all jockey to get 'ownership', which gives them control of who uses it and ultimately leads to non-uniform utilization. This phenomenon is called spectrum warehousing, where some companies 'buy' spectrum just to sit on it as its value increases. The reality is that we are nowhere near capacity for the spectrum we have, although we are subject to some unbreakable physical laws (e.g. Shannon-Harley et. al.). This is one shift in perspective that will happen, that EM spectrum is treated like property instead of a fungible good like air or light.
