This article is not the only report or for that matter even news agency that has reported on this topic. Blue Origin has indeed zero customers at the moment who want to use their services, and the contract is only for five years anyway before it is up for renegotiation.... at which time Blue Origin can try to put forward something of their own that actually can fly.
Elon Musk was so cocky about the whole thing that he offered at his own expense (or the expense of SpaceX and not NASA) to accommodate Blue Origin or for that matter any other American company that might want to use this launch pad for their own projects (referring also to United Launch Alliance). Furthermore, Mr. Musk speculated that the likelihood of Blue Origin actually qualifying according to FAA-AST standards necessary for human spaceflight (which is the only point of using this launch pad as opposed to other locations that certainly are available including at the Kennedy Space Complex at Florida) in the next five years is about as likely as seeing dancing unicorns in that same flame duct.
I have to agree with Mr. Musk on this point too. It isn't just a matter of Blue Origin spending megabucks to build their own launch facility, of which SpaceX has gone through and built three launch pads besides this one and is shopping around for a fourth launch pad in addition to this launch pad (that one is likely to be in Brownsville, Texas), but that Blue Origin is also not really capable of using this particular facility at all.
The whole point of this legal action is to try and delay any potential launches that SpaceX might do at this particular launch pad. SpaceX needs it for both the Falcon Heavy rocket as well and manned launches in particular. It also can act as a back-up site if SLC-40 (the other Florida pad that SpaceX currently operates) needs to go through a period of renovation.
There are another 38 other potential launch sites in the area that are suitable to various degrees or other for spaceflight activity. Some of them certainly are not really suitable and others are in such utter state of disrepair as to be essentially carving out a new spot in the swampland of Cape Canaveral, but there are other locations if the desire was made. There is also pad 39B, but that is currently being used by NASA for the SLS/Orion program as long as that program continues to get funding.
