In the case of applications installed in /opt, data files 
quite often go in a subdirectory of the executable (or a 
subdirectory of the executable's parent dir) and getting 
the executable's dir is the first step to find the data 
files.

This is not only *not wrong* but the FHS prohibits locating 
such files outside of the /opt subdirectory tree, with some 
minor exceptions.

This was pointed out before but since you said you ignore
posts from GG you probably missed it, and will probably miss
this one too, and thus continue to post bad information.
  
This is a small but illustrative example of why such broad-
brush filtering is a bad idea.  But it is your choice.
