Basically reason you have that bonus time is that is time that is low peak less people on, at midnight not many people are online at noon lots are. As far as them doing that I don't see it ever happening the bonus time is exactly that they give you 10GB of anytime data, that is what you pay for and as a bonus you get 10 GB during off peak hours
But then, it's all about the money, isn't it?.That is capitalism in the US isn't it? Always about increased profits every year. Have to be realistic about some things.
I would think that empirical data/graphs of use time, the current trend of electronic manufacturers to push cloud storage so people are stimulated to buy devices that can reach their data from anywhere as well as have a backup in the clouds, remaining capacity of the bird, intent to capture a market share of newer markets out of the U.S., and offerings of the competition has received much more attention in the promotion of current plans than any benefits to the existing or new customer base. The removal of free unlimited uploads may be part of a plan to remold/balance the use of the satellite at the expense of the customers. The anytime bytes with no free upload may be an attempt to shift a lot of cloud storage uploading to the low use hours. Adding a cap to the bonus bytes protects the possibility of that time period becomming used over capacity. The term "balancing the system" can mean more than balancing the gateways. From our customer standpoint it is like buying a large box of cereal and finding it only partially full when opened.I hope my conclusions are wrong but I doubt if your trading bonus bytes at late night for weekends will fly because of the factors above.
