Christopher is reasonably upset. The invention that has brought him the most glory and fame has come under attack, and more and more people have started using a very similar invention. To express his frustration, he distributed an encoded message, that only people using his invention would be able to interpret.
Here's the message:
DSXCE/RVY/UTBMU/CETGDB/CTBGF/WXSESC/ZM/XRVYN/TBNY/YRFHNV/MUYI/XN/TECDF/VYNHG/BVR/YNM/.
What does the encoded message say?
Do you have the means to interpret it? Or are you a traitor to Christopher's vision?
It may help knowing what Christopher invented, but alas, that would reveal too much to make this puzzle any challenge, though I will confidently say that, if you're reading this, you have probably already used his (or his competitor's) invention today.
