No, sorry. This is BS any way you slice it and to defend their move in this direction is even more BS. I get unlimited internet at home. I also work in IT, so yes, I know how finite a resource bandwidth *can* be. However, with network upgrades comes increased capacity. The capacity to handle what you, as a company, promised would be available. Now you're going back on your promise (and even perhaps the responsibility of having to spend money to further upgrade your network) by telling the customer, "Oh...too bad. This is how it is now."
No, sorry, this is BS plain and simple. Unfortunately, whats an even bigger load of BS...is the fact that as people who use this service have absolutely no control over Verizon (or any other companies) decision to do this. Sadly, they (all of them) can and do get away with bloody murder and yet people still support them.
