When I bring up Linux ISOs to the believers of this misconception, they generally argue that Linux ISOs can be obtained without BitTorrent as well so blocking BT is okay. But I believe it is up to the user to decide which protocol to use to obtain the data and if the user wants to use BT but the network prevents this, the network is at fault. Other valid uses of BitTorrent include content intentionally distributed via BT for free by Hollywood studios, television broadcasters, and artists of Creative Commons works. There's also Blizzard patches and other game patches. Some companies like Twitter apparently use BitTorrent internally (https://github.com/lg/murder). Quoting Jay Ashworth <jra@baylink.com>:

There is no legitimate reason for a user to use BitTorrent (someone will probably disagree with this).
Yeah, no.
You've clearly never tried to download a Linux installer DVD.
