The default number of tor hops in a tor circuit is 3. What would be 2GB (1GB + 1GB) of potentially metered/limited bandwidth for the sender(s) and receiver combined in a point to point connection, becomes 8GB of potentially metered/limited network utilization: 1GB for the downloader, 1GB for the uploader, and 1+1GB (down+up) each for the tor nodes in the circuit. Given that tor node bandwidth is a precious commodity, it shouldn't be difficult to see how downloading large files through tor is a problem. It's not just tor; downloading large files by any means through tor hurts the tor network. Tor happens to be by far the most popular means of redistribution of large files for which people would like to gain anonymity.
