This is often repeated fake news.

Take a look at this graph - cumulative deaths since, I don't know, start of 2021 or something.

Sweden is just barely worse than other Scandinavian countries (definitely not 5-7x). Germany is 50-100% worse than Sweden.

So while you might use "total deaths" as an argument that the Swedish "no lockdowns" strategy was worse at the beginning of the pandemic, it's clearly superior now.
