I think the people who have gone OTD are more apparent because of the background of mainly frum people. In places like Brooklyn, there are large numbers of goyim, so someone who is truly OTD blends more into that group; whereas, in Lakewood (like in religious communities in EY) the backdrop is so heavily skewed to the frum end of the spectrum that they can’t help but stick out more, thus it seems like there are more of them.
Hashem should send them and all of us a yeshua and help them do teshuva m’ahava.
