I think you can quite correctly substitute Flying Dog for Brew Dog in the "owner is an asswipe and I won't buy anything from him" stakes:
'BrewDog, the fast-expanding craft beer firm, has apologised to former employees who accused the company and its co-founder James Watt of fostering a “culture of fear” in which workers were bullied and “treated like objects”.' [0]
BrewDog is a sad one for me. It was nice to see a brewery in the region I'm from (Aberdeenshire, Scotland) becoming a worldwide success. But their "punk" aesthetic is a bit cringe for a big corporate company, and the owner turning out to be a dick is a real turn-off and the beer isn't good enough for me to overlook it. There's another brewery in the area that I've been meaning to try out (likely impossible to find in Czech Republic), they've leaned into their Aberdeen identity pretty hard which is cool but idk what their beer is like https://www.fiercebeer.com
