There's more than meets the eye, see my prior post. Why did the FDA not pursue the CC companies too? And if they did, why is it still OK to buy everything under the e-cig sun with CC? Furthermore, are e-cigs and supplies purchased from non-USA vendors safer and why did Paypal not reject them?
The FDA didn't go after paypal, ASH did - and issued kind of a veiled threat about a lawsuit. ASH can't sue paypal for transactions outside the US
There may very well be more to it than that - all I can go on is what's been published.
