>Just today I got one 6s and one iPhone 7 screen repairedNice, except doing a screen replacement on a modern iPhone like the 13 series will disable your FaceID making your iPhone pretty much worthless.
>Previously I got 2017 Macbook Air SSD upgraded using an SSD and an adapter that I ordered from Amazon
Nice, but on the modern Macbooks, the SSD is soldered and not replaceable. There is no way to upgrade them or replace them if they break, so you just have to throw away the whole laptop.
So yea, parent was right, Apple devices are the worst for reparability period since the ones you're talking about are not manufactured anymore therefore don't represent the current state of affairs and the ones that are manufactured today are built to not be repaired.
