Yeah, I imagine she had someone crunch the numbers and figure out that it’s worth it to agree to the union’s demands to get a premiere in the middle of the strike AND the good PR. Sounds like a pretty safe bet.
Now mind you, I don’t really know anything about the situation beyond what I read in your comment. I don’t know what movie that was and I’m only somewhat aware there was a big strike in the entertainment industry in the USA. Just little pieces I caught here on Lemmy and maybe back on reddit too. I’m not claiming to have any particular insight into her motivations or anything, just that what you presented as her good side sounds very much like business acumen to me rather than philantropy.
