What organization/corporation approves all of these releases? I'd imagine Tolkien's estate is extremely aggressive in preserving his legacy, especially if the new books are so different from what's made his novels loved by millions (billions?)
Actually J.R.R. Tolkien's son, Christopher Tolkien, is the executor of his estate and was editor who released both of those works [1]. But, yes, he wants to preserve his legacy, and unlike the recent films, he thinks the published books (even recent) do just that.
