Why did you ever trust anything on twitter without double-checking? Consider how much misinformation you have processed over the years because of too much faith in a platform to disseminate facts over fiction.
I don't think he's talking about the information in the tweets, but the source. If I'm a fan of X and I go find X on twitter, I used to be able to more or less trust that X with a blue checkmark was the twitter account representing X. Before the hilarious shift to the gold marks, it was a lot of sifting through stupid meme accounts.
People were doing verified accounts for my ISP support twitter that day, lol
If we accept the logic that we should not trust anything posted by anyone on Twitter, then Twitter would no longer be a viable source of information whatsoever. Do you see the problem? It is poisoning the well.
someone created an account named USEmbassy_SaoTome and that had twitter verification = that was indeed the official account of the US Embassy there.
consider after Twitter Blue
someone creates an account named USEmbassy_Kiribati and has the twitter blue mark. You dont really know this is an official account. anyone can pay for this
PS: this is just hypothetical I dont really know if those embassies exists.
