I wonder if people here actually read the Discord chats.
There's literally nothing there that warrants outrage.
Speak up if you want different terms, the Analogue guy asked her multiple times for estimates/terms/cost and preferences.
If someone is an expert in a field she/he should be able to communicate the cost clearly. It seems to me she just got upset at a lowball offer, let tension build up and then backed out. Not very professional and honestly quite misleading.
Maybe Analogue should have known better but I don't blame them, this is regular business negotiations, you should not take it personally. Just say no and move on or name your price.
