If you go to:
https://ourworldindata.org/covid-stringency-index
take away the default countries, and instead add Denmark, Finland, Norway and Sweden.
Then make sure you also click "Align axis scales" you will see that Sweden only had fewer restrictions than its neighbors during a very short period at the beginning of the pandemic (during the first wave).
After that, Sweden had both more stringent restrictions than all its neighbors, and had those restrictions in place for a longer period of time.
The narrative - the historical revisionism, the myth that a very large number of people want to promote, and which has even become some sort of amnesiac 'reality' for many Swedes - should not be mistaken for what really happened.
