I would not be upset about that.
I fully expect them to do that since the company transfers the overall rights to the paper to the client upon completion and submission.
I know that they will be submitting the paper in their name and since they paid me for that privilege, I definitely don't have any problems with them doing that.
I would however, be quite upset if they revised the paper I created for them, submitted it, messed it up, got a lousy grade, then the student would come back to me complaining that I wrote a lousy paper.
I prefer that they don't revise the paper themselves since they have no idea how the paper is supposed to flow. If I get mad at the fact that they submitted the paper I created in their name, then that would defeat the purpose of academic outsourcing.
While we are conscious of the fact that what is created for the student is only a "model" paper, our eyes are also open to the fact that the student submits the essay to the teacher in its entirety anyway. Some of them won't even read the essay before submission.
So, provided the student doesn't complain and ask for revisions for mistakes in editing that I did not make, I have no problem with them submitting the paper in their own name.
