No, most of them want to get rick quickly and that's why they choose ICO.
That depends on who ask your information. I don't believe anyone who never told me who are they first before giving my personal details. I made a lot of mistakes previously by giving personal details to anonymous exchange which eventually went down. I don't know what will they do with my data in the end, but I keep praying it won't be used for illegal activities. I'd avoid KYC at any cost, and try to use an alternative option if it's available.
I really hope we can solve this option by making our "KYC" as signature verification, just like Bitcoin/PGP message. That way I only need to send my KYC hash or message which can be verified by anyone in the world. Governments around the world should work together to provide a global hash identity ledger.
