Maybe someone can explain why their SSDs, when not soldered down, are a proprietary form factor and can't be replaced with a standard M.2 device?

I believe they have a special kind of SSD, where the controller is locked into the motherboard. This is serial locked in some form.
(Correct me if I’m wrong, but this is how I understand it)
It’s not actually serial locked, you can replace SSDs by desoldering and resoldering a NAND chip. But basically their SSD controller is integrated into the M-series chips (mostly because cheaper, less connectors to manufacture). But it’s a very specialized process
I think most consumers would happily pay a bit extra for these controllers if it meant that they could manually upgrade their SSDs. I can’t help but have the feeling that it’s also quite convenient for Apple that all this stuff is effectively non-replaceable / upgradable.
I don’t think the benefits are the same as with their RAM being part of their SoC, as that gives them real speed improvements, right?
My understanding is that the controller is integrated into the SoC.
You can actually replace the storage on Apple desktops but it’s a bit of a pain and isn’t as cheap as m.2 2280 drives.
I don’t really know why Apple does this when their solution doesn’t seem to offer an obvious advantage. They aren’t faster than existing solutions or anything like that.
Vendor lock-in increases their profit margins. If people could purchase a 128GB Mac mini and install their own 2TB drives they wouldn't make as much money.
To gain the same effect as one that is soldered down, while giving themselves a simpler portfolio of assemblies and a cheaper FRU to swap in the event of failure.
So vendor locking to make more money. :)
