I hate generic name-text-submit-forms as the only method of contact. Somehow the article makes them the definition of not a "f** off contact page" - why?
I think such forms are a direct downgrade from providing an email address.
- Responding to the submissions likely requires email anyway
- Impersonation/spam is even less difficult
- Sender isn't guaranteed to get a record of sending the message
- A faceless form with unknown machinery feels like sending messages in a bottle
