What did Riogol do that was false advertising? As far as I know, both
scopes deliver more bandwidth than promised and both are excellent
values. Their features blow away the low-end Tek scopes that cost 2x
or 3x as much.
I sell versions of products that differ only in enabled features. So
does practically anybody who sells products whose performance depends
on firmware and other IP that was expensive to develop.
As do we. Our upper end base unit does have a couple of bucks worth of
op-amps that the less expensive model doesn't have but the mobile units are
identical except for the firmware. There are more protections to prevent
upgrading than Riogol used, however.
This was mentioned before, but I worked on the crypto stuff that IBM used in
their mainframes to enable processors based on customer payments. If they
needed more compute power for year-end statement processing (or whatever)
they'd pay for more CPUs and the key to use those computers, for the time of
the payment, was sent to the crypto unit to unlock the processors. A complete
complement of processors was shipped in every box and only the software
configuration determined how many the customer could use (two to ten). As a
bonus, if one processor fell over another would pick up where it left off with
no additional payment required. I guess that was fraud, too.
