I disagree.

Twitter was one of the largest social media platforms on the planet, and was especially huge in the US. Before Musk bought it it didn't show any signs of failure. It lasted over a decade, and had enough reach that I think it made a lot of sense for things like emergency alerts, government officials, etc. to use it as one means, even a main means, of disseminating information. It was really effective at that until what, a year ago?

I don't think anyone really predicted Elon Musk buying Twitter and running it into the ground within a year. Yes, it was hypothetically possible in our capitalist system, but there was no indication that it would until Elon made a joking tweet.

Because of how the modern internet has organized itself, it was inevitable that critical systems would utilize Twitter for it's reach.

I think you're applying hindsight and expecting people to have made decisions based on events that hadn't happened yet. Before musk bought Twitter it wasn't at all unreasonable for people to rely on it for information from government officials because it was the format millions of people were accustomed to receiving that information in every day.
