Fundamental Right to Freedom of Speech and Expression ka Kya Hai?

Main suna hai ki Article 19(1)(a) mein freedom of speech and expression toh hai bas, lekin iska kya matlab hai. Hum kya karein aur kya nahi? Maine read kiya hai ki media ko free speech toh hai, lekin kya hum bhi social media par free speech ka enjoy kar sakte hain? Maine suna hai ki court ne kuch cases mein media ki free speech ko protect kiya hai, phir bhi yeh clear nahi hai ki hum bhi isse benefit kaise le sakte hain. Koi example suna hai jo is point ko clarify kare?
