Because the pattern that emerges with setjmp/longjmp is pretty similar, and that's the most common use: to simulate what other languages offer with exceptions. The most prominent libraries I can think of that force you to do this are image related, libpng and libjpeg both use longjmp to handle errors [though IIRC it's optional in the latter].
If I’m interviewing someone for a programming job and I see goto in there C code... they better have an amazing reason or they won’t be getting the job. Harsh, but it’s reality of how few people are suited for embedded programming.
function(){
// early returns here.
// stuff
// more stuff
if(oops_err){
goto some_error;
}
// yet more stuff
// normal exit
return 0;
// bad exit
some_error:
// clean up
return oops_err;
}

Goto is the typical way to handle errors without creating a hell mess of "hm, gotta close this file, free that buffer, blah blah" at every step where you might want to bail early. There are a few alternatives but none of them are better than goto and a few can be said to be worse.
Denying potential job to a person on a basis of generic "goto is anathema" mantra is not a good idea until one looks at the code and understands what the "offensive" part is actually doing instead of using some code analyzer/text search blindly.
