> Sometimes I just think mainstream media is such an unreliable source of information I am wondering if there are any point reading them at all

Bingo. I forget the name for this law/effect, but at some point everyone runs across a story in the mainstream news about which you happen to be more knowledgeable than the author/reporter/"expert guest" and the veil is lifted for a moment and you think "wow they really don't have any idea what they're talking about!" But then they go on to trust the opinion of these same outlets on economics or foreign policy, etc.

> other than to gather the flow of current society sentiment.

Even this I wouldn't trust. Perhaps if you treat it loosely as "the zeitgeist of manufactured consent" or "what They want you to think is the current society sentiment"

The name you’re looking for is the Gell-Mann anmesia effect.

Sadly finding good sources is very hard to impossible.

What is the mainstream media today? When did they blame TSMC?

I don't know if the media I consume is "mainstream media" but I haven't seen anyone blame TSMC.

Most of them blamed car manufacturers on improper implementations of JIT manufacturing. Toyota is fine because it has a stockpile of critical parts like semiconductors.

From what I've read in the "mainstream media", TSMC is lauded for playing the king game with their foundry model, and pretty much everyone looks shitty for allowing themselves to become dependent on a single company on a seismically active, geopolitically threatened island.
