With all due respect, I'm constantly left scratching my head wondering why people can never find anything better to do than criticize the stuff. Is it great for all purposes? No. Does it have a use? Yes. In fact, some places REQUIRE buckshot.
It gets a little nonsensical. Every time someone mentions the word buckshot online, it's almost immediately followed by someone saying "slugs are better." I know. So do most other people. I've shot two bears with slugs and they were both DRT. But due to regulations or other constraints, some people can and do use buckshot and don't need to be constantly informed of the existence of slugs.
