Convenient consumer products tend to sell better than less convenient ones, even if the product is worse. That's the entire story. People have finite time, so when they receive more income they will tend to spend it to reduce the time they spend doing things that they don't care about.
I for one hate spending time doing all the things that the products in the article make more convenient, and happily pay more so I can spend my time on other things.
* I don't like shaving, so I optimize for razors that get the job done faster (more blades, easier to swap a new blade)
* I don't like cleaning pans, so I buy pans I can clean faster and don't have to "season"
* I don't like filling bags with tea, so I buy tea bags that are pre-filled
* (nespresso) I actually enjoy the ritual of making espresso, so I use a real espresso machine
* I bike every day to and from work, so I take it a step further and buy an E-bike with no shifter
* I don't want to fiddle with chromecast or fire stick, so I just use my TV's built in smart features
* (inner city shops don't sell individual pieces of fruit) I live in SF, it's very easy to find individual fruits here
* I don't like going to grocery stores, so I pay to have groceries delivered to me
My time is precious to me, so instead of spending money on luxury items I spend money to save time. Evidently so do most other people.
