I have seen this process before. I have owned other businesses before, done very well, until they made the same changes X is doing.
I owned a business in the service sector, almost all my income came from 2 customers. The feds and the state. The service sector had hundreds of providers contracted with individually. The Feds and state decide that they did not want hundreds of providers, so the created difficult regulations and expensive accreditation process that eliminated a large number. They then began rejecting invoices for payment because of technicalities, this knocked off another large chunk. This process played itself out for about 5 years.
Near the end we ended up with a few dozen in the state that continued to provide these services. So,,The feds and State say, "not done yet" at the end they ended up with 3 providers,,,, and check this out none of the three were there in the beginning of this process. They each came from large corporate companies that took all the business from everyone, paid politicians for favors, and were given preferential treatment.
If you think X is ok with ISP and the scale process so far and content on leaving it that way, you will be sadly mistaken. If you think being the contractor that will look out for the TM and screw over any contractor around you will keep you safe,,, what a joke, not going to happen. X does not want 5 contractors per terminal, they dont even want one, they want a large capital heavy, stable conglomerate that will provide everything they want under one command. This will take place by region or state over time. If you believe that garbage about not being overly reliant on one contractor mess, well I guess you should ignore this, however once you reach that scale you will basically be X except in name only.
