"Saying something without context" can also mean "not giving the context for what you're saying". If he has any extra information, he didn't share it, which makes it hard to take at face value. If it turned out that this take was extremely wrong, I can't imagine it would affect him at all (beyond maybe making another equally insignificant tweet), so it's not like he's staking his reputation on this or something.

If someone makes a claim without giving any evidence or potential consequences for being wrong, I think it's pretty safe to ignore until one of those things changes.
