Say = story?

No. In this case, the noun say means control, authority. You'd better go ask Mr. Huang, he has more say in these matters than i do.

It's usually seen or heard as the "final say."

It's the last word, the final OK.

Bullshit.

Thank you.

In fairness, I don't think Punkey thinks it's bullshit. I don't think Punkey has read that much.

Actually is means to givie an opinion.

The rest of the sentence alludes to a history (legendary) of micro-managing.

But . . . you can both have your say on this issue . . .

I'm not sure that I agree with your use of "usually", Punkey, but I don't think that your take on this is out of the question.

If I recall correctly from reading various news clippings over the years, I thought that Jobs did have final say on a lot of the products.
