most of the software I consider "pirate" was the software I bought that had known bugs but you only learned about them when you complained to the software/hardware vendor.
Off the top of my head;
Amiga OS 3.5 didn't work with a warp 040 processor
Delpnia Lite needed an 060 to do what they claimed, then later found out ver 3.1 was just junk
Imagemaster R/T won't be retargable until the Amiga OS can do it
ImageFX designed for Cybergraphix software, manageble with Picasso 96, good thing Amiga can handle a lot of windows
Imagine 2.0, couldn't render the darn cow, then they had the balls to ask for a $100 a year continous upgrade fee to finance their conversion to Windows
All of the printer/DTP software, none of them kern due to the OS but somehow Pagestream figured it out.
The browsers all died, too bad you paid for them, with poison pills included.
I paid a lot of good hard earned cash for a lot of software and the shareware I bought still works.
Hats off to the companies that made great software and to those that sold crap I have kept track of you and I refuse to buy your Windows PC software
