I think that these terms are used for a few reasons. I could be either right or wrong, but there are reasons that have little or nothing to do with the opportunity or product being pitched. You've seen them... And if you haven't yet, you will. Take a few minutes to review some sites that claim to make you money online. Eventually you will run into any one, if not all of these terms.
Multiplexes, Matrix, Maximizers, Multipliers, Mega
Here are the definitions that I picked from Websters Online Dictionary. Read them for yourself and see if they somehow fit or make sense to where they are being applied.
Multiplex: being or relating to a system of transmitting several messages or signals simultaneously on the same circuit or channel
b: something resembling a mathematical matrix especially in rectangular arrangement of elements into rows and columns
1 : to increase to a maximum
2: to make the most of
3: to find a maximum value of
4: to increase the size of (a window) to fill an entire computer screen
Multiplier and Mega are pretty self descriptive.
Why the camouflage?
Since it was recognized that there is money to be made online (mid to late 90's), there have been so many scams attached to the original terminology. When most people hear or read the term 'MLM' they get a bellyache. Is that fair? No. But it's still true.
Are there dirty cops out there? Yes. Are they all dirty? No. Same idea. But if someone has dealings with a dirty cop, will they so easily trust the police again? Not if they are approached in the same way...
I think I made my point.
