That's not a useful rate until you factor in population.
"High suicide rate" is a relative term, and does not describe foxconn.
Specifically, the baseline China rate is either 100 or 220 per million per year depending on source. Foxconn had about 14 suicides that year out of about a million workers (or about half a million at the relevant factories? I'm not exactly sure.) That's an impressively low rate. And for reference the US rate is about 100-140 per million per year.
Again, we're talking about a factory that beats its workers[0], faces them down in riots[1], hasn't paid wages on multiple occasions[2], negotiates against mass-worker suicide pacts[3], forces employees into overtime to fatal extremes[4] and blackmails the families of their workers[5].
Maybe, just maybe, giving authoritarian autonomy to a factory complex full of human workers is not a good idea.
Even if you go to the hypothetical extreme of pretending every single one those people committed suicide, it still doesn't give them a high suicide rate overall...
