A very silly minor but accessible thing most people can do is simply downloading their media where they can and enjoying it offline.

If you're a little bit savvy or interested you can start building a catalogue and library of your consumed media that you can access outside the streamed online world.

From there it isn't too out of the realm to explore acquiring or supplementing media from various sources, like say torrents.

Share your library with close friends and family, as one might've lended a CD or VHS before streaming or general internet access.

Start unsubscribing to media streaming services. Use the same expense to directly fund and donate to content creators, causes, and your own damn self for a change.

Offloading media consumption from centralized, ad driven sources is a normie friendly type of effective action. (Beware the Pipeline!)
