Chance you're missing the point that she actually didn't diss Sondheim or Sondheim's show. In fact, she complimented it by asking, "how do you F up ITW?" Implying that it's so good and likable that it's you have to work hard to make it bad. Her complaint was about the actors and musicians. How would that rile up Sondheim fans? I'm a Sondheim Fan and I hated the ITW revival. And I had no problem saying it because it was not the show or SJS that I hated, it was the production and cast.
It's common sense really. I work in a theatre and see lots of things on stage that I have an opinion on. But I use common sense in deciding how, when and to whom I voice that opinion. If I have a good opinion, I say it loud and often to bolster my co-oworkers and the show. If I think the show stinks, I may snark out of the corner of my mouth with the guy at the desk next to mine, if I trust him. But I would never publish it on twitter for these co-workers to potentially see.
Theatre is a small world where people move from show to show, from theatre to theatre. So we are all co-workers, even if we are not working on the same show at the moment. Chances are we will be soon. Or that we have friends in common or know each other. It's just tacky and I can't figure out why some folks are having trouble getting that.
Art has a double face, of expression and illusion.
