The enshittification of streaming is enshittifitentional.
Major B&M retailers of physical media are either dead, dieing, or have phased out physical media.
What a perfect time to issue a deathknell to the whole concept physical ownership.
Streaming originals that disappear will come back in limited release. It'll basically be the Disney Vault of streaming. A company like Netflix would subtly drop references and nods to "removed" popular shows in their new shows to make you nostalgic for the old show. Then bring it back for a couple months.
You'll especially see them all fighting for the best Christmas specials, but they'll pull this shit with Stranger Things by the end of the decade. They expect people to plan-hop and will use limited releases and seasonal specials as their carrot.
