You have made the mistake of assuming mutual exclusion when I for one did not. I am a software engineer and I do this professionally. I am fully aware of the kinds of technical issues, and procedurally issues, which can fully or at least even partially account for its woes. That was not my point. My point was pretty clear and I was very very careful with my exact wording, if you'd care to take a second look at my original comment you've attacked, and probably downvoted, erroneously.
