You seem to be straining mightily to twist this into something it's not.
An author was stopped for coming into the country on a tourist visa when he was actually coming for business purposes. Turned out he was exploiting a loophole in the law, in that the size of an "honoraria" was not defined. By the same logic, anyone who makes a living as a writer can come here to work as long as his salary is classified as "honoraria". And since software is protected by copyright, it seems programmers can be called authors.
No, I don't in any way advocate trying this. Just pointing out the confluence of two loopholes.[1]
[1] Don't like the term "loopholes"? How about "interpretaions of the law"?
