You're extremely lucky. Or maybe you change your laptops before Apple acknowledges the very real problems they have.
So many of their laptops have had issues necessitating recalls, but because they were able to delay those recalls until 5+ years after those devices were released (even if complaints started way earlier), they get away with it.
I've already had 2 Apple laptops where I took in a 4-5 year old device, and basically had them replace/refresh it for free. One was the gen 1 or gen 2 Macbook which had a ridiculous discoloration issue on the case palm rests, combined with the case peeling apart, and the other a Macbook Pro (2011?2012?) that had a graphics card issue.
