The rationale being that if the end-user is not free to fix the product, then the end-user is not the owner. The end-user has merely rented the product. The manufacturer is still the owner, and thus is responsible for the cost of repairs.
If you have a large family, it makes sense. For most people, this is gonna be a miss for them.
There's no rule saying you have to be related to watch the movie together. It makes sense for most people if 4+ of them (at $13/ea ticket prices) are willing to get together and watch as a group. I have a 5.1 home theater system with a projector that throws a 12' x 7' image, and that's exactly what my friends and I occasionally do.
The fly in the ointment isn't the price. It's the entire concept of watching movies at home. When movies only came out in theaters, you had to watch it while it was still in theaters. Home video, subscription cable, and and now streaming has changed that - you can now watch a movie which hasn't been in theaters for months or years any time you want. My queue over all streaming services is about 100 movies long (never mind the episodic TV shows). I'm more than content to watch other stuff while I wait for hit movies to show up on the streaming subscription services. The only exception I can think of is the reason my sister gave for taking her son to watch The Force Awakens on opening night - so he wouldn't be left out of conversations when the other kids in school talked about it.
It's conceivable that a parasite that has evolved to control host behavior could have adverse psychological effects on human hosts, thus the research into it.
My theory is that it modifies the behavior of human hosts, causing them to dismiss the idea that parasites from cats could modify the behavior of humans.
