This might be a strange question, but why is Zorro so unknown?

I only happened to stumble upon it by chance recently and I am amazed at what it can do.
It basically addresses all of the gaps that other more common trading software like MT are having, e.g. the possibility for meaningful backtests, parameter optimization and statistical analysis, not to mention a much more elegant and practical syntax.

So why is not everybody using Zorro?
Or are they and just nobody has told me yet?
