Yes, I believe that would be correct. Apple is plural in the sense that it is made up of multiple people acting in unison. Same as "My family are visiting over Christmas."

However, the word Americans is not a group of people in the same sense that USA, England, Apple, or family is. Its kind of like the distinction between people and persons.

Edit: the term for words like family is "collective noun". More at https://blog.harwardcommunications.com/2017/02/07/the-family...
