BitTorrent traffic was restricted through bandwidth throttling using the SCE-2020, and in later years, the SCE-8000 from Cisco Systems Inc, which had caused complaints as users felt Rogers was overstepping their bounds as a service provider and despite Rogers advertising their service "for sharing large files and much more". Rogers had previously denied such allegations, despite widespread reports of the issue. Further controversy arose when in May 2007, Rogers began throttling all encrypted file transfers allegedly to combat BitTorrent traffic, but affecting all encrypted transfers regardless if they are BitTorrent traffic or not.
