Understanding "Intermediary" in IT Act - Help Needed!

Maine ye question 3 baar padha aur abhi bhi samajh nahi aaya 😭. In textbooks, it's written that an intermediary is a person or entity which provides services in relation to online content, but koi clear example provide nahi karta hai. Sabhi textbooks mei likha hai ki intermediaries ka role social media platforms, search engines aur email services ke beech hai, but itna vague hai. To please, apko lagta hai kya koi real-life example hai jo is baat ka concept clear kar sakta hai. Like, kya Google ko intermediary maanta hai? Kya YouTube par content post karna wala channel owner intermediary hai? Koi sahi example bataye please, taki main understand kar sake! 😩
