They will if NO ONE does them, or if companies can't get anyone to apply for a seat that is required by law (FAR's) to be occupied.
You weren't putting someone else out of work by doing that - interns don't replace full time workers.
If you pay to occupy a seat (a la gulfstream academy) that would normally go to a paid pilot, that's when people get upset. Some people get upset with people paying to occupy a seat for which they aren't required to be there because it allows those companies to underbid other, more upstanding companies.
Since we're really only dealing with ethics and morals here, and it appears you have none and would rather pay for a shot at a job instead of earning it, the opinions are all subjective (with the exception of the monetary issue, as another issue highlighted).
