You're excited about the prospect of repairing a manufacturer's faulty engineering at your own cost?
An analogy would be buying a new car then bragging to your friends that despite it being a lemon, you're thrilled because you can repair it yourself (at cost).
You’re missing the common alternative in the modern age which is the manufacturer not selling the part at all and being left with a pile of unrepairable junk despite an otherwise functioning device.
Laptop hinges were notorious for killing laptops for like a decade.
"Lemon" was never mentioned. That's extreme. I don't care what make and model of car you choose, I'll show you a list of TSBs associated with that model. There's never been a car produced that was perfectly engineered and had no after-sale issues common to that model and year. There's always something.
Yes, I would be thrilled to find a car that gave cheap and available replacement parts so I could remedy those issues later. That used to be the standard! The trend now is for automakers to keep juicing the proprietary software tools and one-off components, making repairability harder for the owner.
So, to rephrase your analogy: "[That's like] buying a new car then bragging to your friends ... that you're thrilled because you can repair it yourself (at cost)."
