Oh there's no problem paying somebody to do a job. But somehow you'll need to be able to check that the job is done. Or at least read the opinion of somebody who has no stake in the matter to attest to the job being done.
So "the job" here involving making a browser not do things, which you can't see. How often pray tell do you pay somebody to perform a job you can't verify the outcome of, but take him by his word that he did it?
