I agree, this entire thing looks very blown out of proportion to me. It's not the first time and not the last time there will be malware in a brand new game torrent on 1337x.
This exact situation has happened before with a new game torrent that had malware, torrent eventually got taken down, and nobody raised a huge fuss other than not to download that torrent.
Because Firefox on mobile is a pile of shit to be honest. It works great on desktop, but the mobile experience is subpar. For a chromium browser, Bromite used to be an option, but it seems abandoned now. Brave is one of the few Foss chromium browsers left that also supports adblocking.
