If I was stuck here with either no paperwork or waiting on an application, but miserable, I'd find this (and the support CuriousaboutSamphire is talking about which may involve this) far better than waiting on hoping something would get better or hoping the embassy of my birth country would repatriate me (which some countries force people to take out loans to cover the costs to do, whereas this could cover the plane ticket and then some).
It's not saying "fuck off back to where you came from!'", it if you're in a precarious, vulnerable possibly illegal situation, we can support your return, possibly to where you have a better support network or a country obligated to do more for you.
The Home Office fucks up a lot, but not this. I mean the list of people includes victims of modern slavery. Some of them come from the EU. Do we really want to say it's offensive for the government to have this framework for them and anyone who similarly might need help to leave just because it involves giving money to help people leave the UK?
