Footsteps is not to “make people OTD”. It’s to help people who are ALREADY OTD to integrate into secular society and help them find college educations and jobs, etc.
Project Makom visited my community a little while ago. I hosted a few of the participants for Shabbos. They were very sweet and sincere but I had a hard time relating to them because their backgrounds were so different than mine. And they did have a LOT of questions. Which I think is a good thing.
