Can't say I agree with the judge on this (based on the contents of the article and not reading the links). Whilst I agree, it's reasonable to expect the usable space to be less due to the filesystem overheads, the question is, when there's manufacturer-installed stuff on there, how can we know how much that is? It's one thing to expect an amount of loss due to filesystem overheads, but software is another thing - I'm reminded of some of the 32GB Surfaces, where you lost *half* the storage due to the OS and pre-installed apps.
As an example of doing it right, I have a Sony Walkman S639 MP3 player. That's marketed as "16GB", but it also says (in letters nearly the same size) that it has XGB* of user-addressable space after taking into account the OS and filesystem.
* I can't remember the exact amount - it was marginally more than 14GB, I think.
