Well, KYC is needed in order to ensure that they are not involved with corruption, bribery, or money laundering. To think it has some good advantages but some really want to be in anonymous and this is why we can see different opinion/s.
Well, some investors prefers kyc and some or most of them don't want this. They have their own reasons why they like or don't like this. But the decision will still be base on the team, what requirements are really needed.
I guess if the team prefers KYC then it will be beneficial to all the people who supports the project. If you're a normal person without anything anomaly I bet you will agree to KYC.
