Well, it´s a matter of style then, Orlando.    I personally have nothing against the use, and certainly people would understood both ways, tough GOES perhaps sounds more natural.

     a) In informal way we can use, but usually in academical assignments/projects I would suggest to use the third person (singular) after the "more than one person".

     b) I have noticed too that when it comes with a modal verb in the sentence, then the following verb don´t take the "s". 

     c) Other cases may be exception to the  rule, but then, are exceptional cases. 

      I would go for the logic, but somewhat seems like the Portuguese logic we are using; like the "You are" by our Portuguese would be "You is" because in Portuguese is "você é".         English is really tricky sometimes, beat me!

But as more than one person has pointed out, none of these examples — with the possible exception of Google and search — meets any kind of real test of the term monopoly.
