You say that usually it is the case when one bigger corporation buys a smaller one that the customers benefit in some way. I would argue this is almost never the case. The steady march towards monopoly only benefits shareholders and upper management. They might throw some scraps at customers in order to gain support or drum up excitement, but that's all they are: scraps.

Anyway, I'm sorry to hear about the shitty situation there. I hope you guys can figure out a solution.
