Part of it I'm sure. She blamed it on a mix of nasty comments about her body (probably boob job stuff), constant leaks on social media, and not having time to run the page anymore since her sister moved on, who always ran her OP and passes for her.
But big picture I think she just wanted to move her career in a different direction. She's been saying she wants pivot her career now she's getting older since early last year, then this year she got her media company and started doing a bunch more golf media and business stuff behind the scenes, so my guess is she would've stopped passes anyway.
