TBF, I don't think anyone expects a TLDR to contain the same nuance or detail as a 30 minute video.
TLDW: The Phoebus Cartel established 1000 hours as a baseline to get maximum efficiency. longer lasting bulbs would require WAY more power per hour to operate while producing less light.
Planned obsolescence is indeed a thing, but using this as an example of it is incorrect and discredits the overall argument. It's better to focus your attention on right-to-repair laws for your $2000 laptops and $40,000 tractors than on your $2 light bulbs.
I've heard stories about people putting out old appliances and furniture out on the curb with a "free" sign. It sits out there for 4 weeks. Then they put out a sign that says "$20. inquire within" And an hour later it was stolen.
