I get it. So they just changed everyone to be half a plan above where they chose to be. If these people wanted more data, then they'd have chosen those more expensive plans with more data, but they didn't, so Verizon chose for them. It's like ordering a medium size and they say "oh, we give you more than medium, so you pay us more, no? Don't break contract or you pay us more then too. Have a nice day."
I won't use Verizon mobile because of poor policies like this. I have a non-verizon plan that has unlimited data... but only the first 3GB is fast. After that, it's slower. I asked Verizon how I could make sure I don't pay more than my budget for data and they said I could have them turn off all data at 3GB or pay their relatively expensive overage charges. So they won't have my business.
