It's explained right in the post:
"After 2019, RT shifted the primary score to a "push" notification via ticket processors like Fandango. A ticket buyer walking out of the theater gets a prompt: "Did you like the movie? Tap 1 to 5 stars." They tap a star, and they're done."
There's no significant boycott, there's only a handful of perpetually MAF losers like you who are still spinning about this and even reading the gamegate subreddit in 2026 LJL.
And they didn't go to special lengths, it says they've done this across the board, because of bitter, angry dorks review bombing shit they haven't seen.
This is a great example of why you people are impossible to take seriously. You didn't even read or comprehend the post you're citing; you just saw numbers and the title.
