Skimming through it this seems largely a description of historic and broken cryptography and almost no information about practical modern cryptography.
(also the obligatory note: no HTTPS for a webpage about cryptography?)
Except that it's not even that. You're right that a lot of crypto is broken, but usually because of implementation bugs, not because people use vigenere ciphers.

Think of it as "cryptography in practice." And in practice, it's often broken, whether from poor implementation or design flaws.
