The thing is, taking down the ebooks is less about avoiding spoilers, and more about encouraging people to buy the re-realease.
Like, let's say they sell them in sets of 10 or whatever. Someone buys it, and are all "Hey, this series is great! I wonder if there's any communities!"
They go online and find RAF, along with the ebooks. Suddenly, they're thinking "Well, what's the point in buying the rest if I can read it for free online?"
Then the re-release doesn't do good, and there's less chances of 2.0 coming out.
Sure, it'll still be possible to get the books for free online somewhere, but why make it easier when the sales for the re-released are going to have an influence on whether we get 2.0 or not?
