What sort of argument is that? Just because I need to eat (also let's be real the developers/owners behind this app are not struggling to get food on the table), does excuse me doing unethical/illegal things (and this behaviour is almost certainly illegal in the EU at least).
The guy that holds up people for money in the alley is a human too, people forget, and needs to pay for food and a place to live. Of course they do too.
