I think it's best to look at the term “free” as referring to the degree of restriction, or a hypothetical lack of restrictions. Within this broad definition, the meaning of an instance of the word free can vary.
Here are some examples:
"No cost" or "no price" - this is the most common meaning of "free." You’re ability to take it is not restricted by a cost.
"Freedom from constraint" or "liberation" - this meaning refers to there being “few” physical, social, or political constraints.
"Unconstrained action" or "autonomy" - this meaning refers to having the ability to act without being restricted by external factors.
"Unburdened" or "without obligation" - this meaning refers to having no restrictions from responsibilities or obligations.
The term “free” is frequently used for its positive connotations and emotional appeal. The positive connotations of "free" are often justified because they are associated with the concept of a gift. In many cultures, giving gifts is seen as a positive and generous act, and so the idea of receiving something for free can be seen as an act of generosity on the part of the giver.
In addition, the concept of "free" can also be associated with the idea of freedom and autonomy, which are also valued in many cultures. The idea of being able to act without constraint or obligation is seen as a positive thing, and so the word "free" can have positive connotations in this context as well.
However, “freedom" is often used to manipulate people by appealing to their desire for autonomy and unconstrained action. In political discourse, for example, the term "freedom" is often used to justify policies that benefit certain groups while harming others. By framing these policies as promoting "freedom," politicians can appeal to people's desire for autonomy and unconstrained action, while masking the fact that these policies may actually limit the freedom of others.
This use of "freedom" to manipulate people is often based on a narrow and individualistic conception of freedom, which focuses on individual autonomy and unconstrained action, rather than a more expansive and community-oriented view of freedom, which recognizes that the freedom of one person may be limited by the freedom of others.
Additionally, the use of "freedom" to manipulate people can also be seen in advertising and marketing. For example, companies might use the term "freedom" to market products that are meant to promote personal autonomy and unconstrained action, even if these products actually limit people's choices or constrain their behavior in other ways. In these cases, the positive connotations of "freedom" are being used to manipulate people into buying products that may not actually promote their freedom in any meaningful way.
