Software piracy existed long before the internet and it simply moved from offline copying to bulletin boards to internet-based FTP sites, Usenet and IRC and such once that became common and now I guess mostly P2P.

Bill Gates famously ranted over hobbyists that copied Altair Basic interpreter that he had part in developing back in 1976. Not the first occurance of piracy either, but maybe the first time anyone actually described it as stealing.

The use of the word “piracy” describing unlicensed copying dates hundreds of years back, to book plagiarism and copying. Much later also applied to music bootlegs.

This is not the right community to ask “why?” in.

I suspect that there are more than a few thousands URLs to if you want to go down that route.

The URL is likely unique to identify you as soon as you have clicked.
