Also the shareholders overrode Ben and Jerry against their objections to sell. They didn’t want to. Of course they probably shouldn’t have gone public in the first place but if they hadn’t you never would have heard of them. Unless you grew up in Vermont. Like me. It was kinda weird seeing a beloved business become huge. Like watching Phish go from a local band to something giant.
