Has anybody done a bit by it comparison between firmware in the 50MHz
unit and the 100MHz unit to confirm this?

Probably not because it is bleedingly obvious that it was IDENTICAL from the
simplicity of the hack that has been explained in detail. If you have
actually
looked at the eevblog and are still asking this question then you are a bit
thick.
Also, Rigol have apparently reacted and changed the firmware to stop
the simple hack. So all roads lead to Rome, so to speak.

Hacking your own property is both legally and morally fine. Telling the
world how to do it is more of a grey area but this is only one case of
many. Using that information to buy 50MHz units and sell them on as
100MHz one would probably be a crime.

Just because the US has draconian laws on the subject doesn't mean that
those of us who live in saner parts of the world should have to comply

Certainly it may affect the sales of their more expensive unit, but, if
they have any sense, they will just drop the 50MHz unit and sell the
100MHz on for the same price or a few dollars more and blitz the market.

But FJ is alluding to the possible effect on Rigol's sales of their phoney
100MHz version.

FJ's claim to the contrary is entirely RIDICULOUS !!

IOW - a clear case of guilty conscience induced paranoia.

IOW - the colossal fool protesteth far too bloody much.
