Sure, but people generally aren't downloading torrents on cell phones. Apple devices make it very difficult (torrent clients are explicitly excluded on Apple Store for iOS), and while you can get torrent clients on the Google store, people aren't using them for live video as far as I know.
Cell phone TOS usually explicitly prohibit peer-to-peer sharing, and I got my so-called "unlimited data" Sprint service cancelled back in 2010 for exactly that.
As long as peer-to-peer on phones is rare, nobody will notice, but if somebody spun up a competitor to TikTok that depended on serving video FROM phones to the rest of the Internet, and it started to get significant traction, I think the cell phone companies would bring an end to it.
most of the time infamous for its abundance of “linux distros”
What the heck does that have to do with watching viral videos on cell phones? We're talking about a competitor to TikTok. With respect, Linux is like 3% of the desktop market, anything happening on Linux endpoints is noise to the big players.
