Exismailis.. what made you leave because Ismailis are so strong in their faith

Edit : To everyone who are listing their reasons.. Could you also please give me some inside information that I could use to help my friend? Since I’m not ismaili myself I don’t really have insider information which I think will be very useful in trying to question her. Or make her think.

To everyone who left this faith. What made it happen? I’m asking because I have been around Ismaili people and I’m not Ismailis myself. The more I found out about how things are the more I was like tf is this. But all the Ismailis I see are way too involved and they can’t even fathom the idea of becoming distanced from this faith so it makes me wonder the exismailis were once ismaili too and they must also have been insanely attached to this faith and followed it by heart. My ismaili friends always tell me they will only become closer to this faith but never distanced. So with that level of passion/brainwashing.. what was the “reality check” or the little “shock” that made you leave or distance yourself from this faith?

I’m also asking because I want to help my friend out of this idk whatever tf it is.
