@Francisco 1. The freedom to study how the program works, and change it so it does your computing as you wish (freedom 1). Access to the source code is a precondition for this. - the JavaScript is served in obfuscript form without function names or comments or indenting, thus understanding the program would require reverse engineering and doing so may be illegal.

2. The freedom to redistribute copies so you can help others (freedom 2). - no license means you are forbidden from redistributing it by copyright.

3. The freedom to distribute copies of your modified versions to others (freedom 3). By doing this you can give the whole community a chance to benefit from your changes. Access to the source code is a precondition for this. - you don't have freedoms 1 or 2, so you don't have 3.


These freedoms may seem odd by those used to having them taken by proprietary software companies, but all users deserve them and should demand them.
