I remember reading about it in an article where they got their hands on a "guideline document" for an expo (One of the big Java ones) for Sun/Oracle people.

In it it basically talked about the need for constant low-level differentiation and playing-down of scripting languages.

The link you posted above is the kind of thing this encouraged. Don't be actively hostile but more "Oh, a scripting language? How cute"

Sounds reasonable but a bit outdated. Then again who would've guessed that historical ubiquity of JS scripting language would eventually put it on server side?
