Those links were just laughs.

She's notoriously supported the overall narrative & movement she's now taking a stance against for years via Harry Potter and social media until she supported someone who got fired over a tweet and making her "true feelings" known in 2019:

"J.K. Rowling has long used the Internet to tweak the Harry Potter universe she created, surprising fans with trivial revelations from Ron Weasley’s patronus to the fact that wizards used to poop in their robes."

"The author has previously caught flak for tweaking the Harry Potter canon, often via tweets and the Pottermore website, to include more socially liberal details. In 2007, she declared to fans that Hogwarts headmaster Albus Dumbledore was gay, a detail she doubled down on this year but that never explicitly made its way into any of the books or films. In 2014, she similarly “clarified” that there were Jewish students at the wizarding school. Some have criticized these edits as self-serving, but Rowling’s tweets have seldom been called malicious. The backlash she faced after Thursday’s tweet was especially notable, given the prevalence of the LGBTQ+ community in the Harry Potter fandom."

Before that 2019 tweet, everything was gucci and she was seen as a strong supporter of the LGBTQ+ community, to the point where Harry Potter had it's own sub-fan "queer community" within the fan community, which again, Rowling did know of and support via social media:

“I think the queer Potter community is tired,” wrote Darcy, who identifies as bisexual and genderqueer and has been active in Harry Potter fandom for most of their life. The books “meant everything” to Darcy as a kid. As an adult, they worked for Harry Potter fan organizations."
