I'm not fundamentally going to disagree with anything you've just said,
equationgirl - I've seen shittiness in the retail end of the drinks industry and although I've no idea what goes on in the big breweries, it would hardly be a surprise if they're not havens of enlightened staff treatment and equality.
But I think you have to look at this as not just one big homogeneous industry. No one expects Carling to be anything but a lowest-common-denominator-pleasing corporate. That doesn't excuse them if they're unethical, but the root of the particular anger with Brewdog isn't that anyone thinks they're uniquely terrible but about how much it jars with their self-presentation as independent, craft brewers doing it for the love of it. And not only are they bullshitting everyone but they tarnish the image of the part of the industry they're pretending to be part of - in fact, pretending to be the main standard bearers for - that really is full of people doing it for the love of it and keen to do business differently: if you've ever read any of the trade and promo beer magazines you'll have seen multiple articles about LGBTQ-run breweries, zero-carbon pledges, circular economy, etc. I'm not saying there aren't bad 'uns there too of course, but I think it'd be very unfair to assume every company that makes beer is part of whatever iceberg Brewdog is the tip of.
Having said that, TBH, thanks to Brewdog, I'm now wary, possibly unfairly, of
any of the 'crafts' who've managed to get their wares into major stockists nationally - Tiny Rebel, Camden, Northern Monk, etc. I'd rather stick to what's in the local independent bottle shops and tap houses even if I can afford less of it.
