Exactly!
It's not only the lack of creativity and effort that gets me, but also because I bet S8 would be pretty annoyed if JK Rowling and Warner Bros. "created" a series of for-profit 'Dragon Chronicles' movies, starring the (very familiar looking) Flame Dragon and Cubic Zirconia Dragon. They have ten days to complete a series of tasks in a story-like format to save their brother dragons, and they play Bingo in their very limited spare time!
It's like the golden rule of fan fiction: if you make money off of it, it's wrong.
The FFS (and I looove that abbreviation, lol!) HP event was much worse, as far as obvious infringement goes. I dropped that game soon after seeing that event.
