Looking only at the aspect that we have one company copying the exterior design of another and selling a different product within these design parameters has different consequences, IMHO.
First ... the light can be confused with the SF offering. If this is intentional or not, it can cause issues for those who are less educated than we are.
Second ... the performance and perceived value of the two offerings will bleed into the other, meaning people buying this thinking it is SF and vice versa will think differently of the manufacturer, and not because of their own product, but because of the product of the other.
Third ... a company doing such a copy on purpose shows questionable business ethics. If they have no problem doing this, I can imagine a lot of other things they are also capable of.
I won't do business with such a company as this design copy's negative implications are not worth my money.
It's not like they couldn't have done it differently, they didn't want to. As a consequence, I don't want to have anything to do with them.
Just to point out the obvious copy to all those in this thread who are not familiar with the FS M3T:

P.S.: the head scallops are copied from the KT1.
P.P.S.: not that I wouldn't want that light.
... as it sounds very interesting and "just right" indeed.
