I LD_PRELOAD (and DYLD_INSERT_LIBRARIES) code into every process I spawn from the command line, except setuid executables (and sometimes even then–I jump through the hoops necessary to make this work), because it lets me extend compiled applications in arbitrary ways to better suit whatever I want them to do. Saying that my usecase is "outdated and…intellectually bankrupted" just because you're not aware of the very real and very convenient benefits of function interposing is the real ignorance here.
