I don’t think it’s shade though, I saw it too and I thought it was a pretty objective description of what happened. If you had no idea what happened you’d simply think she had left ‘somewhere’ (because she doesn’t mention SBS) because she didn’t like the direction of where it was going and set up on her own. She’s allowed to talk about it, it happened to her. I think she’s been pretty dignified about it all tbh
. As for not speaking badly of previous employers I think that only applies in job interviews.
