When it's the original author or within a reasonable time frame of their publication the concept of rightful owners makes sense.
The idea of an essentially immortal non-living entity or a 5th generation niece/nephew being a rightful owner to a work is not a view I agree with. Society is the background that allows works to be created, at some point control over those expressions is ceded back to society.
Markets don't always work, but here's a place where they've worked exceptionally well. We are in a wonderland of available content. It has never been easier to find something great to watch or listen to. If Disney wants to charge me $100 to watch Steamboat Willie, what do I care? I'll just watch something better, and probably not pay anything for it.
All art is based upon the past. Think of how many times the plays of Shakespeare have been remade and reinterpreted. His works represent a share heritage that generations of artists have freely borrowed from.
And Shakespeare did the same thing! Hamlet is based on a 13th century legend of Amleth. Should a high school production of Hamlet in 2022 be required to pay royalties to the 13th-century chronicler Saxo Grammaticus?

I agree but I don't see why a reasonable fixed term, such as 25 years, wouldn't work as well and allow the cultural well to refill. Think of how liberating it would be to be able to, for example, freely sample music from 1993 or earlier. And every year we all get more!
It's just not a strong argument.
Don't forget: you were paying for Charlie Brown last year when it ran on network TV; you just weren't paying the same way you are now. This is really just a story about how broadcast TV is being obsoleted by streaming; it's not a copyright extension story.
If we are citing legal trivia the original constitution of 1790 allowed for a copyright term of 14 years, with a single extension, for a total of 28 years. So the halloween special would have entered the public domain in 1994.
Consider the cultural difference between the gen-x experience of "every gamer" knowing the first level map of FPS game "Doom" vs the experience of never meeting another human playing in a procedurally generated space game like Elite Dangerous or No Mans Sky.
We can all entertain ourselves alone and very cheaply, its just if none of us have anything in common there is no more "We" anymore.
The effect can also be seen in political divides and other areas of life.
In the linked article, they intentionally, for some reason, confound "Friends" and "The Office" as common cultural experiences. However, even that is false. Friends finale in 2004 had 53 million viewers, The Office finale (US version, 2013) had a mere 5 million viewers. Quite a rapid cultural implosion!
