Genuine question. Why is this important to note?
I personally didn't care for the limited beer choices they made available to bars, but some of the things available in their tap room in SF were really good. It's a shame to see them go, though I think more in the "sign of the times" way than the idea that I'll actually miss their beer.
But today Anchor and Shiner are objectively not that great compared to modern craft-brewed beers. I still drink them mostly because of nostalgia.
But I also miss when there was shelf space for a range of import beers, instead of 30 feet of IPAs with different circus colored labels...
Heineken, the world's #2 beer producer, bought them for ~$1B (half in 2015, rest in 2017).
