请教anything other than,anything but,和nothing but的解释

selfmotivated

做gwd的时候遇到这个句子
It is doubtful whether an investor’s sniping at management can ever be anything other than counterproductive, but in this case it is clearly not justified.

anything other than 是只是的意思吗?那么anything but,和nothing but的意思呢?困惑.

非常感谢!

我觉得你最好能够举一些具体的例子.没有语境，我不敢肯定。
不过我觉得anything 的那两个说的是除了后面的内容，nothing说的是 只有后面的内容
