Good question that I didn’t notice was mentioned with any unifying reason in the article. Oberto sold to a Canadian company in 2018. I gathered Remo’s was impacted by the Covid virus. Mentioned lightly in the article. So that is my assumption.
I didn’t see much in the article either. Even if it was, you have to wonder if what is stated in the press is the true reason. Maybe the best reason is just time and the Italians were absorbed and combined into the oppressive whites. The US used to be a melting pot. Don’t see that happening anymore by design.
