From what I am seeing on the Internet there are some scopes that the 
software limits them but to get the full bandwidth some components need 
to be changed.  I bought a China function generator and while it does 
not have a software upgrade there are several components to be changed 
that make it function better at higher frequencies.

 I heard some cars have functions that can be turned on and off remotely 
so they can charge you yearly.

The sat and cable TV is like that .  The equipment is the same but they 
only enable the channels you pay for.
