Elon didn’t burn down Twitter. It still has 100m+ users. He turned it into a politically far right echo chamber, gas lighting its users about “free speech absolutism,” and then outright banning, demoting, or drowning out commentary he doesn’t agree with.

Unless you meant “burn down” in the sense of “turned it into the ashes of a trash fire…” but it was always a trash fire. People still go for it, and advertising still happens there.
