If I could easily do this on my desktop/laptop I legitimately might stop pirating media. I would also stop if the streaming companies just let me watch full quality and didn't take away what I purchased because the rights holder decided they want you to buy it again on another platform.
I don't mind much paying for streaming (although that's increasingly more and more annoying and I still tend to just download whatever I actually care about) but until and unless I can pay to "own" a movie and they just provide me with a DRM free video file of some sort, I will never "purchase" digital content like this.
If you tried this kind of bullshit in just about any other context, even normal people would think you're crazy.
Normal Person: "hi there, one blender please. I'll take this one for $25."
Sales person: "Cool here's your receipt."
NP:: "It says here at the bottom of the receipt that you can just come in my house and take this blender back whenever you want or maybe never?"
SP: "yep."
NP:: "And you don't tell people that ahead of time?"
SP: "no when you buy it you agree to that by opening the box and it is on the receipt you get after you bought it."
NP: "you fuckin with me rn?"
SP: "afraid not, and would you look at that corp says I need that blender back, thanks."
SP: "oh, shoot. I see here you also bought a toaster from EvilCorp sold in one of our EvilMart locations a couple years ago, we've decided to license that brand instead to our new partners FukUMart, so we'll be taking that toaster but if you want you can head to your local FukUMart and buy that toaster again for more than you paid the first time."
NP: spontaneously combusts
Anyone who has worked in retail will tell you this is absolutely, concretely, and vehemently something corporate would expect their employees to actually say to customers, so don't go giving them any ideas...
