Rowling's "rage-tweeting" (in other words, her opinion) hasn't hurt her fortune and her IP one bit. Universal's Wizarding World has been enormously successful, so successful that it's being expanded upon in Epic Universe. And a new Harry Potter TV series is in development at HBO. And the Hogwarts Legacy game withstood the wrath of, um, some and became one of the top-selling video games of all time. So Rowling's doing JUUUUSSTTT fine.
If anything, Rowling dodged a bullet by not letting her IP being dumbed-down into a Midway Mania shooter attraction (actual Disney plans, I believe). Universal respected her input (unlike Disney) and built a true wonderland. One that truly fulfills fan's expectations, unlike Galaxy's Edge. Bravo, Universal, for not bowing down to the mob and for not doing a cheap half-baked version of a worldwide publishing phenomenon. Universal gets all the wins.
