Is "bit rot" appropriate as a term to describe how software on a mobile phone appears to degrade in performance as a consequence of receiving updates which are intended for a more powerful hardware platform?
I am torn, since I always understood this term to refer to the degradation in the performance of an immutable piece of software as a consequence to a change in its environment.
In the example given above, it appears that the change is the other way around, and so a degradation in performance is experienced due to the hardware of the platform being immutable and being pushed to its limits by greater demands in the software.
