Treehouse is almost definitely in that conversation as well. Hill Farmstead as well.
The uproar is probably more among folks who follow the industry though. Most people have seen Anchor at a grocery store at some point. They were, I'm pretty sure, a natural niche craft brewery before those things were normal. In the same zone as places like Sam Adams or New Belgium or Sierra Nevada. You didn't have to really be "into beer" to know what they were and maybe enjoy buying a Christmas Ale from them every year as a seasonal thing.
To OP's point, there's less places like that now, but that's because I have 3 local breweries I'd be sad about if they closed, instead of 1-2 national breweries. I'd be sad if Trillium or Alchemist closed, but it's not as if I could buy them without traveling to the area, so it's more of a "aww, that's a bummer" and less of a change to my life.
I'm not sure either is better/worse though. We've just moved beyond the sort of craft beer monoculture. We don't just have 2-3 Christmas Ales we all drink, in the same way we don't all watch the Macy's Thanksgiving Day Parade or all talk about the new episode of ER every week.
