What can he do, all he has done since leaving (thrown out) is "activism" he is unemployable and I can't imagine he will be able to get a good job in Croatia. He cannot sell himself as a content creator as he had people to do that for him. He can clean windows I suppose, but he'll have competition by the JW's in Croatia as it does seem to be a niche market captured by the JW's.
He's had well over a decade and a half to establish himself in his new country. He could have learned to speak the language. He could have got at least some part-time employment to provide himself a reliable income and work history. Lets face it - his activism is not and never has taken a full-time amount of effort. Everyone else who produces exJW content does it in their spare time without making a song and dance about it. Most of the time he wasn't even doing any of the admin or production work and just farmed it all out to volunteers, so what exactly did he do all day, besides play with himself?
