No, chosen means "chosen" in this context. Reliance defense is only one of the many offset partners. There is a long list of them. Did the government strong-arm Dassault to go with all of them? Something tells me that Dassault will have much better things to do.
French government said that there was no pressure on them. In such an important matter, I am more likely to believe the government than a news agency I have never heard of.
