Can't say I'm surprised, it seems to be the way of things these day that big business want's to screw every last penny out of their customers.
Model seems to be to hook people in by offering free services and once people start relying on the service or it becomes indispensable charge exorbitant fees.
I've been looking at Fusion 360, a very good commercial standard 3D drawing package. It's free to schools, startups and hobbiests but they won't say for how long it will be free. So you spend ages learning how to use it (with most of the of the teaching is done for them free by customers answering questions their forum) and then they'll suddenly state everyone has to pay the commercial rate of something like 5000 USD/year.
By the way ... didn't see you at the BBB this year!
