You might be right (or at least closer to it) if the current POTUS didn't regularly use Twitter to make actual policy pronouncements with significant real-world consequences.
Trump used Twitter to threaten thinly veiled war with North Korea in response to North Korean missile tests, and yet a few months later he was shaking hands with Kim Jong Un.
In some ways, Trump's use of Twitter to A/B test would lessen the impact should a hacker gain access to the account, since most people would probably just dismiss it as "Trump being Trump".
Anyone treating Twitter as a gospel truth is an idiot.
"Justice Department lawyer Jennifer Utrecht in her reply [in a Supreme Court case] acknowledged the president’s tweets are official government statements"
