Access to the source code is a precondition for this.●The freedom to redistribute copies so you can help your neighbor (freedom 2).●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.
