Regarding Lenovo: I bought an original Macbook Air. It always worked well. As it got on to about 10 years old, I took it in to an Apple Store a couple miles from my house and asked if they could replace the battery. The battery worked pretty well, but I figured.. the machine was going strong and if they still had batteries in stock, I should grab one now and the laptop will live even longer. They replaced the battery…
These are not comparable. There are wildly different quality of laptops under the Lenovo brand. A ton of them are complete crap. Apple simply doesn't sell anything like that. The author is comparing to a Thinkpad specifically.
Additionally, the 10 years old Apple that made your macbook is a very different company from today. Although they are still a premium brand, the reliability and replaceability of parts is completely different. I have one of the first unibody MBPs from 2009, and ran it for almost 10 years (although I had to switch to freebsd and linux by the end because of Apple). That laptop was incredibly sturdy, and parts were reasonably replaceable, keyboard lasted 10 years before getting squishy. Battery was a terrible hot pocket but replaceable without screws! back then it was all SATA so I upgraded to an intel SSD from before they sold their controllers to samsung - also in a user serviceable compartment next to the battery.
None of these things are true of Apple laptops today.
