Not very honest and straight-up...and if the picture is actually that of the spoke - that's a 7.0mm elbow that'll snap no matter how much tension is used whether thin steel flange or basic alloy hub.
I'm charged at the latest .0750 apiece for a 14g spoke in lengths of 200mm to 310mm - and I do not vary my wholesale or retail price likewise unless I cut and thread again.

So why does the 7mm elbow fail? What is the reason? How much stress must you apply for it to fail? And how different is the fatigue stress at the elbow if it's just 6.2 mm or 7mm at the elbow? And why wouldn't proper tensioning alleviate and cold-set the spoke heads correctly to relieve the stress prior to cyclic loading and thus reduce long term fatigue? I don't disagree with prevailing theories on spoke line and elbow radius, but I believe it's a second order effect that is far smaller when compared to quality of steel and forging process to make the spoke.
But the price is attractive. Not many places offer that low of a cost for spokes.
