It affects it in that prohibition of reverse-engineering is no longer an 
option for those who wish to redistribute software that links with even LGPL 

LGPL does taint the resulting executable--if not the source code used to build 
it--by allowing any user to completely and totally reverse any executable 
linked in with any LGPL'd code and re-write portions of it to suit any 
internal need.
