I'm doubtful of this premise, especially in the context of peering disputes. Here in the states, Netflix had/has serious issues with Comcast/Verizon/Centurylink not peering with their upstream providers sufficently to handle the number of video streams that needed to be carried. This was not an issue with the last mile connection itself, but a middle mile peering problem. From the testing I have done, on certain carriers that play games like this (Deutsch Telekom in Germany, Centurylink, Verizon & others in the US, and most Asian/South American ISPs) torrenting updates to users is significantly faster than an HTTPS download from Amazon, Google Cloud & the like. Once you get a handful of seeders internal to the network, the other downloaders in that network start to get the torrent significantly faster than they would over traditional HTTPS. If the content isn't extremely time sensitive (eg: live sports games, video calls) and is of a noteworthy size, using P2P tech to speed up downloads is not a bad idea.
