I may do a blog writeup about this (partially because @admin has asked me to and partially because most of this is ridiculous).
I can see how they think it looks like they're being more generous than before with the new plans, but they are advertising it wrong.
Old plan: 512kbit/s for first 100GBs, then down to 256kbit/s
New plan: 1mbit/s for first 25GBs, then change back to 512kbit/s
These plans should NOT, I repeat, SHOULD NOT be advertised as a 1mbit/s plan. It should be advertised like it is: as a 512kbit/s plan with a temporary speed boost.
