There's a difference between oversharing...and barely sharing anything.
We've said it here for years - most here are actually not saying "give us everything about your personal life". It's just natural to want to see your favorite star a little more than a few times a year. And, social media is how he built his fanbase, and he did a brilliant job at it. No, he's not obligated to do anything he doesn't want to do, but keeping a reasonable public presence and connection with your fans is simply good business (and a reflection of good representation), especially these days (and esp. between projects). It wouldn't exactly be a bad thing to find that balance...and I doubt anyone here would be complaining if he did. For example, more photoshoots, more interviews, and attending of events.
That said, we're all very aware he's grown up, changed his stance on things like social media, and I'd think most of us here respect that, especially in regards to his mental health.
But yes, as a fan, I'm not going to lie that it would be nice to see him just a little bit more.
