For me, while I am curious of other religions, I don't have an interest in practicing one. Being a JW my whole life I kind of assume that all religious orgs will have nosey busybodies like JWs and I have been spied on and bothered enough. It's hard to put yourself in the path of another group that may cause you the same trouble, and I feel like there is just as much conditional love out there in other groups.
My curiosity for religions led me to research Zoroastrianism. There was no mention of this group by Watchtower except that Darius (from the Daniel book) was Zoroastrian. (And so was Freddie Mercury). But just a Wikipaedia read through on this monotheistic religion from the middle east, and you can note similarities to Judaism and Christian teachings. It made me question the Bible and what I had known of history. It also was a trigger for me waking up. I even tried to talk to Witness friends about it. "Have you heared of this religion? Why have we never read about them before in Watchtower publications? I wonder what the Org would say about them!" I could tell they were uncomfortable. And here I thought we were also supposed to research these groups beliefs to better Witness to them, so what's the big deal?
I also spent this past year working in a Christian school and part of that included attending chapel with the students once a week. I never had to conduct religious instruction. They did ask if I was a Christian after giving me the job. I liked that I could sit and hear basic Christian teachings without any pressure to join the church and reevaluate what I may or may not believe or agree with and I liked a lot of things about their worship. But I still remain unmoved to join another church.
(I hope I didn't go too off topic here)
