If we look at the TrueCrypt audit report: https://opencryptoaudit.org/reports/TrueCrypt_Phase_II_NCC_O...
It says they found 2 high severity issues, 1 low severity issue, 1 undermined severity issue. All in the cryptography category.
There were additional issues found by the Project Zero: http://googleprojectzero.blogspot.de/2015/10/windows-drivers...
Even when faced with this clear evidence, people consider TrueCrypt as being safe.
VeryCrypt is under active development, so the situation is much better since the issues can be fixed in the future releases. However, people might blindly follow whatever is reported and consider VeraCrypt bulletproof regardless of the previous experience with other crypto projects.
