Calling reusability "a dream" is different from saying "Starlink is impossible."
You can try to read the tea leaves on tone and some creative interpretation of implicature (despite Starlink actually needing fewer than 1000 satellites for its public launch), but they're different claims.
Not sure why there's a need to exaggerate the victimhood of SpaceX lol, super strange.
The Ariane guy was quite clear about what he thought was practical and not. He said $5MM launch won't happen (it didn't). He said reusability is a dream (he was wrong). He said nothing about the impossibility of Starlink, either implicitly or explicitly.
