EX4 security issue?

 

Hey all! 

I was messing around on a site with some free stuff what a friend sent me, and I found a PointZero indicator for free that drew my attention and I noticed something that gave me a surprise, the "cracked" indicator showed a comment on the chart that says "Free On <>" and I then thought that was nearly impossible that PZ added the comment and then compiled it to then share it for free, but I'm also curious about how they added that to a compiled file? Then I remembered that some time ago someone post something about copyright protection by using string chains to print stuff on the chart so if someone opens the ex4 on a text editor they cant change it, and although I opened the ex4 with notepad, and indeed it showed the link to the PZ site I didn't found any naked string there that can be changed or something! 

Any ideas? I'm pretty surprised that someone might have actually decompiled the file

Pd. I'll attach the indicator and a screenshot.
