Selling your brewery for fabulous amounts of money to a big multinational isn’t a problem — it’s doing so when you’ve made capital from being opposed to just that kind of thing.
If you had made a point of saying along the way, ‘We would never rule out selling to someone like AB-InBev — we have no beef with Big Beer,’ then it’s unlikely anyone would get annoyed when you did so.
So why didn’t you do that?
It must have been at least partly because you believed you’d gain less publicity and adulation, and sell less beer.
You might have been right to think that, but we suspect not: the other way, you’d gain marks for honesty, and pick up the kind of fans for whom beer isn’t so pungent with politics.
Either way, if you insist independence is important when it benefits you but then decide people who care about it are silly and immature when your situation changes, expect them to be annoyed.
