One long running fan project that is pulling the plug because of this is "If the emperor had a TTS". Here is their statement https://m.youtube.com/watch?v=OXljeaktnDA
Yes they were using GW’s IP creating the series, however without that series they wouldn’t have another fan of the lore and in the end another customer.
I dunno how to feel, I can see GWs side, it used their IP, copyright and IP law allows them to restrict derivative works. But without those derivative works I wouldn’t have given a shit about GW
They say “don’t bite the hand that feeds you”. And GW can honestly feel like they are feeding these fan works with IP, however these fan works are also feeding GW with customers.
