I don't have much to say about the points you're making here. I have a feeling after we sit down and discuss this over coffee/a beer we will find out that we're pretty much on the same page.
The only thing I want to point out though it that the term "enshitification" was coined for online platforms. It describes a business catering full hog to the needs of the users to create a following, then sell access to that following to other businesses, until both followers and b2b customers are locked in and get milked for every cent possible. From the user POV that's when the service enshitifies ~~DVD~~ and the b2b customers are between a rock and a hard place. Your cable example follows a similar mechanic but since it is not online it is technically not enshitification as dumped into the world as a term by Corey Doctorow.
That's just minor pedantry that you're naturally free to ignore as well. As I said before, I don't see us disagreeing on the overall point you're making. Very eloquently, I might add.
Edited typo
The absolute worst airports to navigate are all in the US. Fort Worth, Atlanta, just to shame two.
Most other airports are easy to navigate, even on your first trip. It's basically walking to a door with a number following huge signs with arrows and numbers. If you need help, you just ask staff working there. The Lufthansa people will be delighted to take a biz class passenger by the hand. Make sure your suitcase gets sent to Korea directly, pick a seat you like (aisle is better if you ask me), and don't forget your passport. You'll be fine!
