Your overuse of the word "technically" puts me in mind of a defendant in a courtroom saying, "Technically, your honor, I was swinging the bat to loosen up my shoulder muscles. He could technically have gotten out of the way, if not after the first hit, certainly after the second or third."
Technically the stated purpose for X can be whatever, the actual purpose is what matters. People have the idea that all law and ethics relies heavily on the wording of edge cases, but it's just not so. The vast majority of both law and ethics is based on plain and simple understanding.
The plain and simple understanding of a general-purpose torrent client is that it is for piracy. Is there a 0.0000001% use-case for Linux ISOs (on your phone!) or what have you? Sure, but those are the edge cases, and are easily satisfied using Safari on iOS.
You could technically light a fire and use a blanket to send smoke signals that use morse code for hexadecimal numbers that represent a uu-encoded representation of an .MKV file for the latest blockbuster too, but that's as unlikely as anyone emailing a gigabyte of pirated content to a large group of people, so it's not really worth considering, is it?
