Its called torrenting my friend. Real control, real offline, no proprietary DRM bullshit
I have used years ago different download platforms, years before Torrent, in the time of Napster, Emule etc. but so far the official streaming service provide a good offer, without wasting time. I don’t think it worst the effort to download illegally ie comparing with price of Prime. I see now a tendency when the platform cost will increase and users should, in theory have 10 platforms, where i may understand the reason for people returning to illegal download. The streaming service companies should think carefully before increasing the price or creating new rules to share the cost.
