WordPerfect and Spectrum Holobyte explicitly cited software piracy as being worse on ST than on other platforms.
WP did eventually come to the ST and if I recall it was panned as a horrible port. I think there was talk of MS Word, too, and also a flop?
Mine came with 1st Word Plus, and it was excellent for the time.
There was a port of MS Word, and it worked well. For some strange historical reasons I can't recall now, though, it was called and marketed as MS Write instead.
Write was the extremely basic free wordprocessor in Windows 3.x -- and so the name did the ST version a grave disservice.

Nothing with the power of WordPerfect.
Hundreds of word processors were developed for DOS. Hundreds. Word, WordStar, and MultiMate, all developed by very large companies, were only the best known.
WordPerfect beat them all.
Feel free to claim that the ST or Amiga word processor developed by two guys somewhere in the UK has more features c. 1989.

I do a bootable DOS system on a live USB key and it includes Protext. :-)
It was certainly popular, but I hated all the function keys (I still hate function keys) and my favourite was WordStar (not for Windows), for both word processing and as a programming editor, up until I switched to Word and Windows vi clones.
I remember the CP/M version of WordStar gave you a patching tool that allowed you to insert screen and keyboard handlers in machine code, for your specific hardware (to speed things up), into the WS code. I can still remember how clever I thought I was when I got this to work!
Piracy always exists. The question is to what degree. On the PC the bulk of the market is business customers, where piracy is relatively minor compared to legitimate sales, and corporate customers have a lot of power when they complain to vendors; this is why copy protection more or less disappeared for PC business software after the mid-1980s, with Lotus being probably the last to comply by getting rid of the universally detested key-disk system. On the ST and Amiga the business market more or less didn't exist (no, musicians on ST, or small-town TV stations using Video Toaster for Amiga, aren't meaningful in number or percentage by comparison), so potential sales are limited by a) the far smaller size of the overall market and b) the far smaller percentage of customers within said smaller market paying for the product.
The same rubber domes and plastic plungers were Totally Unacceptable on the Sinclair ZX Spectrum+ and QL, Not Very Good on the Atari ST and Commodore Amiga, and just what everyone uses on PCs today.
I dunno man. I came from a ZX Spectrum (via several other machines, it's true) and compared to that, the ST keyboard was great.
