I don't feel as if there was so much of a dominant paradigm back in 1987, when RISC OS first came out, at least not outside of the US?
I recall that period more as a melting pot of ideas and approaches from lots of manufacturers independently trying to figure out what paradigms might stick.
There were many disparate approaches to text-based OSs: MS-DOS, Acorn MOS on the BBC which is the predecessor of the shell found in RISC OS, Sinclair, Atari, etc. Likewise, separate approaches to GUIs: Mac, Gem, RISC OS / Arthur, the Amiga, etc. Windows 2. Teams from Acorn, Research Machines, Sinclair etc all basically did things in their own way.
While the Macintosh UI paradigm was considered dominant in some market segments at the time (eg DTP), there wasn't yet a universal expectation around how GUIs would work. That started happening more after Windows 3 came out, in 1990 iirc.
Certainly there must have been cross-pollination of ideas between these different groups. Pretty sure these Docks and Task Bars with icons, that we all have at the bottom of our screens now, was an idea first seen in RISC OS.
