Yes, glossing over critical issues by showing off buggy, insecure code is the very best thing you can do to a beginner.
And tutorials are an excellent opportunity to show off the ease of use and elegance of a language. I never start learning a programming language without sampling some code first to see what I can expect, and if you can't find good code in the official documentation, where can you?
