In this question, the asker seems to be asking about how bandwidth usage is counted. A possible misunderstanding of its accounting may have led the asker to believe that if bandwidth is "used" by the uploader, then the downloader shouldn't also have it counted against them. The question, "Isn't this double-counting?" may arise and lead directly to the titular question (paraphrased), "Why can't we upload directly without it counting as a download?".
Regardless of what exactly this person is asking, the fundamentals of downloading, uploading, and bandwidth seems very relevant to home networking, and thus, SU. Why is this question considered off-topic? Could someone clarify?
