According to the article: "About 80 percent of bank deposits are denominated in euros and Zagreb’s main trading partners are in the eurozone. Croatians have long valued their most prized assets such as cars and apartments in euros, displaying a lack of confidence in the local currency." So in that sense it's less of a radical change than e.g. Czechia or Sweden, since they primarily use the local currency AFAIK. If you're already half-way using the Euro (kuna is pegged to Euro as well) you might as well join the euro-zone and have some influence.
