No, but is differentiating products on softwar supplies any different from
differentiating them on hardware?  Cheap ones simply wouldn't be available to
hobbyists if they had to sell them all as top of the range, where they make
the money for the effort to make a high bandwidth scope.  There is also the
advantage that they can perhaps be hacked by well-informed hobbyists, but most
commercial buyers wouldn't be happy doing that for one or another reason.

 
AFAIC, it *does* matter if the limitations are in hardware or
software. In the case of scopes for example, good  bandwidth don't
come cheap! So if you're going to go to the expense of developing high
bandwidth capability it just seems like self-mutilation to cripple all
that hard work to produce an inferior product.
 
 

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.
