Any knockoff sold is the loss of a sale to the guy that developed the real thing .. there is simply no other way to look at it .. thinking otherwise is humorous .. it's like saying a movie studio does not lose money to pirating in all it's forms ..
As well, you will find, if you care to actually do any research, that name brand Corporations in many, many cases, aggressively go after the knockoffs of their products .. the two you named do ..
What people fail to think about is : if you essentially went thru the process of developing a product, then the marketing of that product, then the discovery that your product was a success and that you might actually be able to make a living with it .. ask yourself, would you be happy when suddenly knockoffs started appearing at half or less what you sold for .. ?? Place shoe firmly on other foot, then, rationally answer that question ..
I have to somewhat disagree with that. If there weren't waiting lists for the higher-end mechs and attys, I'd feel differently. There are possibly thousands of Mona Lisa prints out there. I seriously doubt that should the Louvre put the original on the market that they'd have trouble finding a buyer.
There are tons of "kit" cars available and you can build your own GT40 in your garage for a fraction of the price of an original; put an original on the market, and you can almost name your own price (Steve McQueen's GT40 got $11,000,000 last year at auction).
People will still line up out the door for the latest Atmizoo, regardless of how many they pump out the door from fasttech.
Nothing says the two guys in Greece can't have it produced in China. Not a THING. Almost every single company out there has at least some items sourced from a 3rd world country.
True, but it wouldn't be the same. I think if folks found out that Mojo was just buying his mechs from Shenzhen Young June Technology, sales would plummet. They buy his mods because HE makes them.
