Is 'find useful' elliptical?

[konungursvia]

It is elliptical, but that's not the ellipsis. It's "find to be useful."

Mr. Ayed,

There would be nothing wrong with the syntax, and a native English speaker might say that, but there is the problem of the unclear antecedent to "them", which in this case is not a reflexive pronoun but a pronoun acting as the object of a preposition.
The hearer is left a little puzzled by the two possibilities for an antecedent -- "Manufacturers" and "consumers". Logic indicates the second, but it is not perfectly clear.

I hope I was not off the point..Thank you very much, Frank.

[Frank Antonson]

You were not off the point at all.

I think it was a good question. In many ways "them" DOES seem reflexive.
