I more so meant her:

1. lie that she never indicated Hermione's race (when a controversy came up about a black girl playing Hermione in a stage production of Harry Potter) even though it's clearly stated she's 'pale and white' in the books - in an attempt to look diverse
2. The lie that she stated Dumbledor was 'always' gay just so she could look more diverse, though no indication was ever given - With Rowling giving the statement along the lines of 'That's how it should be' to cover herself.
3. Talking about Dumbledor and Grindlewald's 'Incredibly intense, passionate, love relationship' to really sell he actually was gay all along.
4. In 2016 Rowling published The History of Magic in North America, a four-part series of writings on Pottermore about magic in the New World from the 14th to 17th centuries. She plundered Native American legends to tie the wizarding world into the setting of the upcoming Fantastic Beasts debut, so it was 100% a promotional exercise.
