These are static wicks, and you are correct that they do bleed off static from the plane. That said, they cannot handle a lighting strike and when one of those puppies hits an airplane it usually leaves a small hole where it came in and a larger one where it went out.
It can also weld a lot of stuff inbetween like control surface bearings, throttle cables and so on. The larger airplanes do not have these (for the most part) but the inspection on a plane after a strike can be rather extensive.
Still, it happens almost every day with no problems...
