We do not want to be assumed as an any other ICO out there in the market. You can check most of the ICOs have linkedIn and github links.
If you go through those links and read more about their identities or technology, you understand either they use fake identities or illegally use identities of other researchers from CS.
You should let your investors worry about whether your team's identification is fake or not. Fake IDs are easy to spot. By not providing the information, they cannot do the necessary due diligence, and the risk of being scammed is too high.
Furthermore, knowing your team not only prevents people investing in a scam, but also let's them know the likelihood of the team succeeding in implementing their idea and bringing it to market (the idea is the easy bit!)
