Why are official company support forums so useless?

I often get better results from community forums like Reddit, Steam, StackOverFlow, StackExchange, GitHub, 4Chan, etc. Hell, even mainstream QA websites like Quora and GaG nets me better answers than official support forums from Microsoft, Samsung, Acer, Google, Amazon, etc. Like I literally had some clown in Samsung Members troll me by trying to gaslight and strawman me, just to prevent me from placing blame on the company for my phone's problems. And a lot of these official forums lack basic features like blocking and muting, so I either stop using them or just do whatever I can to get banned.
