That's a crazy attitude. People who use pirated software will not buy Mach4, they will do their best to find a pirated copy. Period. People who don't use pirated copies will not buy Mach4 because of the uncertainties and the nuisances it cause with the limitations on licensing. It would be MUCH better if it was sold with hardware dongle, or a smart software dongle, which would NOT lock the license to a specific computer hardware and should NOT limit commercial use.
...in the meantime, since I posted last time in this thread, I bought a UC300ETH with UCCNC. I know now that Mach4 is out of my game for me and is no longer something I consider ever buying. Mach3 and UCCNC is all I ever need... well, "ever" is a very long time, but today I can't really see to ever wanting it and definitely not until the license conditions are not changed.
