Where do I get the bit about commercially viable?
Well, directly from the story.
Again, a "snag" didn't stop them. That was another thing put in the story to add to the "mystery"...
The reality is they often don't get a profit from towers in my area, not for a long time. They do, however, get to show that their footprint is better and businesspeople from other areas will select their service so that people can get information out in the boondocks... It isn't phone tower in this area goes up and the 50 people that can reach it will offset the cost. It is: People in the area own 14 businesses with over 150,000 total employees between them, with service being available they maintain service on our network, if we don't put it in and AT&T does we lose "x" number of users on our network.... blah, blah...
How many of those 20 parcels of land have people who are fiscally powerful on them? Would they get their companies to transfer to their network because of availability? How much would that offset costs? Would they transfer their company's service away from the network if a competitor added service first?
But hey, you think that it is all just "simple" because you never worked for a phone company.
There are myriad other considerations. Reaching a "snag" simply meant it was now going to cost more because of impact fees, etc. They then determine that the benefit from the footprint wouldn't offset the cost overall because of added fiscal requirements from impact fees and other determinations that they would not know about until starting the process.
Making this some sort of conspiracy to commit phone service is just outrage over nothing happening.
