I'm an old millennial that downloads and keep what I like. It took so long to download anything on dial-up that the habit was to keep everything for later.
And then because I go camping and cycling in places without network coverage, I took the habit of copying a few hundred of MP3s and a few dozen episodes of cartoons on my phone. That way I have some entertainment even when I'm in a forest without network coverage.
I still can't understand people streaming music on their phones, music that they probably are going to listen and download again and again and again instead of only once. Why not keep it instead of constantly using bandwidth for the same thing over and over?
Same with watching stuff. Your favorite paid streaming service may eventually decide to remove a series you like, or miss a few seasons. That's if it's not on another streaming service. Like, I know I'll watch and rewatch again episodes of the Simpsons, so I download them. It only consumes bandwidth once and can watch it on repeat whenever I want, even without internet.
You can still pay for stuff, but don't use the DRM ridden streams that can disappear or can't be accessed without internet... pay for it if you wish but then, pirate and download a version you can keep.
Or I'm just old and living through "bandwidth scarcity" and really owning stuff left its mark on me.
