You can "do whatever you want with this code", but there's a catch: you have to give credit to the original author. You might not care about the credit, but lots of people care. You can't just cherrypick the things you like about a license. All of the conditions of the license apply. You're thinking about what people can do with the code, like copying, editing, and distributing. This is not it. We're talking about giving credit to the original author, as per the license.
