Free Javascript?

Dice Stallman:

Javascript itself, as a format, is free, and use of Javascript in a web site is not necessarily bad. However, as we’ve seen above, it also isn’t necessarily ok. When the site transmits a program to the user, it is not enough for the program to be written in a documented and unencumbered language; that program must be free, too. “Only free programs transmitted to the user” must become part of the criterion for proper behavior by web sites.

Comprensibile. Anche condivisibile. Terribilmente difficile.
