What were the market forces or limitations that led to NFS prevailing?

​Sun pretty much gave it away.   It was simple and 'good enough.'

The Issue was it not a real UNIX file system and did not support full UNIX semantics.   For a lot of things (like program development) that was usually ok.  It also exposed a lot a issues in user code - things like programs that never bothered to check for errors returns (like fclose).

So bad things happened for a long time in a lot of code (silent holes in your SCCS files that did get detected until months later). 

But to Sun and NFS's credit, it solved a problem that was there and was cheap and so folks used it.
