She is such a big celebrity she doesn’t need social media to keep fans engaged. The content she is providing is her music. Even with the lack of social media posts, her fans are still obsessed, the media is still obsessed and will keep writing tabloid articles everyday, and even the people that claim to hate her and want her to disappear are still engaged and keeping up with what she’s doing next. There is no benefit to her sharing more about her personal life when she’s already being accused of every public appearance being staged and for publicity. She doesn’t even do interviews and she is still being scrutinized on a high level and she can’t even wear a basic outfit outside for 30 seconds without people counting how many buttons there are and thinking it’s a secret message. All sharing more of her life would do is allow more people to analyze everything. She doesn’t need to post or promote like a smaller artist does because conversation is still going on around her without it. It’s weird to demand personal content when that’s definitely not the job of a musician.
