IMO they'd sell more accounts to people, who are undecided between "no account" and a "cheap account" and not to those who really want so much traffic; there is less uploads to RS and decreasing.
Those, who needed more traffic could get it automatically, without any interaction. Easy, comfortable and eve cheaper with the old conditions.
I don't believe that a single customer wanted the recent changes, RS is simply lying. I guess they were too stupid to explain their pricing-model with buying additional traffic. Now they even keep the HappyHours a secret: to complicated to explain this?
During HH it's 1500 GB traffic per month, who needs that?
Fucking liars
