this is fundamentally false. The LGPL was created because of static linking where GPLd code would be in the distributed binary.

It's an open question (the FSF has their opinion, but it has never been adjudicated) if the GPL impacts dynamic linking.

One could argue that if one ships GPL dynamic libraries together with one's non GPLd code, one is shipping an aggregate and hence the GPL infects the whole, but its more complicated to say if one ships a non GPLd binary that runs on Debian, Redhat et al and uses GPLd libraries that they ship.
