Very small fraction of people who rip other's code provide the proper credit, so I'm not surprised that KSDev's original developers succumbed to this practice, which eventually led the code into Delphi.

However, I'm surprised that the code made its way unmodified. The code itself is poorly written. What was doing Embarcadero's QA department when this code was integrated? Perhaps the code's quality assurance is not part of Embarcadero's business practices?
