According to the article, they didn’t try very hard

“The expropriation of Carlsberg and Danone serves those two companies right for not having had a clean exit, as they should have back in 2022,” says Professor Jeffrey A Sonnenfeld from the Yale School of Management. “They stayed on too long. They were trying to be clever. Danone paid lip service to being critical of the war, but then stayed there with perhaps half its business. It claimed to only keep its dairy business in Russia, but what else does Danone do? It doesn’t do automobiles, clothing or jewellery. It is a dairy and yoghurt maker.

“Carlsberg was even more cynical than Danone, since it pledged to leave Russia early on into the invasion. It was a poster child of early-mover courage and conscience, but six months later it had nothing to show for it. After public criticism, it reconsidered again and was close to selling but was then expropriated by Putin.”
