The PRUs were really hard to use. I think if they had invested in dev tools with a shallow learning curve, like Arduino support for the PRUs, they might have gained critical mass. The Beaglebone Black was pretty nice compared to contemporary Pi's for embedded work: way more GPIO pins, with female headers rather than male (lower chance of accidental short circuits; easier to just jam components or wires in there like it's a breadboard.)
