C.e.c - matter of opinion

Freedom of speech and expression, therefore, may not be recognized as being absolute, and common limitations to freedom of speech relate to libel , slander , obscenity , pornography , sedition , incitement , fighting words , classified information , copyright violation , trade secrets , food labeling , non-disclosure agreements , the right to privacy , the right to be forgotten , public security , and perjury . Justifications for such include the harm principle , proposed by John Stuart Mill in On Liberty , which suggests that: "the only purpose for which power can be rightfully exercised over any member of a civilized community, against his will, is to prevent harm to others." [7] The idea of the "offense principle" is also used in the justification of speech limitations, describing the restriction on forms of expression deemed offensive to society, considering factors such as extent, duration, motives of the speaker, and ease with which it could be avoided. [7] With the evolution of the digital age , application of the freedom of speech becomes more controversial as new means of communication and restrictions arise, for example the Golden Shield Project , an initiative by Chinese government's Ministry of Public Security that filters potentially unfavorable data from foreign countries.
