'No earlier than' is pretty standard for rocket launches. Not weasel words, but actual scheduling/contract terms.
OT
Sounds legit, until you stripped off the context from the Spaceflight Now article: "Officials have not announced a launch date for the Falcon Heavy’s next mission".
By definition, the public is mislead when even interested parties like
@winfield100 misremember the details: he recalls the date reported by CNBC but forgets the "no earlier than" part, because its added at the end to de-emphasize its importance.
Honest reporting puts that caveat up front, and emphasizes that, as Spaceflight Now did in their story, that
no launch date has been set, so a 'missed launch date' is not even possible.
News that's engineered to mislead is misinformation. When reporting consistently targets one company while ignoring similar events from competitors like ULA, that reporting is part of a misinformation campaign.
This story sets up CNBC with the convenient option of ignoring whether the Falcon Heavy launch meets
their timing, or writing a followup headline that
"SpaceX launch delayed again" if they don't launch on CNBC's timing.
So "pretty standard" reporting for the manipulation managers at CNBC.
TL;dr weasel words.
