For many people anonymity is important. It is because they do not trust the companies that collect and use personal data of users.
Very often appear information in media that personal data was stolen. That is why people want anonymity and do not want to provide personal data.
The KYC procedure for each person should mean that everything will be honest and safe from now on, but more and more often personal data becomes available to scammers.
KYC itself is not terrible, its a completely different question to whom we share the data and whether it is safe, all personal information of all users should be carefully protected.
