Obviously I have strong feelings about this, but, let's look at this another way. How much money would WotC gain by having a "fair" price, which, just so we are very clear, charging me even remotely the same price for a version that once produced, is free for you to make infinite copies of, should not be valued anywhere near what the nicely done hardback books regularly sell at, which is around 33$.
Now, weigh the difference between 9.99 for the PHB only character editor, sell the expansions for each book somewhere between 1.99 and 9.99 on the editor, that describes the options, but not the mechanics, so you still need the books in question. And compare it to the 30$ that WotC is selling each digital copy for for a net loss of 20$ per sale. While this is all true, the other side of it, is that the thing, once made, costs negligible amounts to distribute, and how many more people will buy everything., like myself at that "fair" price. Compared to how much indemnity they are creating by removing that option, which is right and good, but than not supplanting it with a comparable product. Not to mention, the added benefit of making it intrinsically easier to introduce new players., increasing your customer base.
