I think you might be the one not getting a few things. Which would be fine and no crime except you presumed to lecture someone else from this weak position.

First off, this was a different user. Second, they are simply saying that they didn't read the title that way either originally, not that they don't grasp what has been said since. Third, it is still a perfectly valid way to parse that sentence even using your attemped re-framing.

"Foo from HN releases X" could perfectly reasonably be parsed to mean that X is coming from HN or from Foo. I left out the word "user" because that is an element you added that is not in the original title. "Stennis" is not a mere individual user with no actual relationship to NASA. The title doesn't contain enough information to indicate if Stennis is merely the agent or venue or department through which NASA released something, or is being referred to as it's own distinct entity releasing something of it's own, where "NASA" is merely something like the country it happens to live in. All that level of detail comes from the article or from just happening to already have prior general knowledge of NASA and it's sub-organizitions.
