It doesn't matter. They were published and their rights were sold by JRR Tolkien. You've established several times that means he was okay with them being adapted. You are the one that argued the rest of the legendarium doesn't matter as in the past you made a distinction between published and unpublished. Now that your argument includes published work they can be included. When it was my argument that included them you excluded them. You flip flop on what matters depending on the argument of the moment.
If it doesn't matter what he intended because he is dead then why are you still arguing that it matters? Isn't it strange how you keep contradicting the points you make? Including saying how much you want to stop discussing but apparently can't actually stop.
