The ESC does use a compressor, and it doesn't just move the air, it pressurizes like the other two forms of FI do.
The only major difference between the ESC and a turbocharger is the fact that the ESC is using an electric motor to spin the turbine (powered by additional batteries) rather than using exhaust gas pressure to spin it.
I'm not sure why I'm feeding a troll, though...
EDIT: Looks like others beat me to it =/
To add to what I said above... obviously a turbo is more powerful than an ESC, and can build much more boost than the ESC is capable of, but it doesn't change the fact that the ESC technology isn't fake. It's also relatively new technology, and we have only begun to see the potential in it. Once batteries become even more powerful and efficient, and as the technology is developed even further, it may surpass the other forms of FI in the future.
