In my eyes one of their highpoints which demonstrates their trustworthiness is the ~20 million dollars payment they received this year by undisclosed European (I think it was European) entity (government or private donors maybe)
And to be fair not all Come back alive projects are long term, they provide cars, cables, laptops, portable power stations etc., but these do not engage public enough, so their media team focuses on more interesting projects.
What "long term" means is also differs, they put a lot of effort into their training centers, but now the training cycle of one person is several months (I assume, I don't know exact terms), which is not that long.
