Well, it's pretty clear in the WP that they will charge 1% annually which the OP failed to read. It seems he also refuses to believe the references I've already posted judging by how he is still waiting for confirmation and why he isn't locking the thread yet.

Whether it's unfair or not is another matter, I have a good grasp of why they do that but I won't speak for the team. you can question them directly or you can also read the WP.
