Those folks you mention seem to deliberately use "no lockdown" to describe Sweden, when clearly (I linked to a source, and gave personal observations) there are restrictions, and so is more accurately "light lockdown". I can't help but wonder how it came to be used in this title.
BTW, I looked for mention of upcoming substantial changes at https://www.gp.se/ and found https://www.gp.se/nyheter/sverige/platserna-i-g%C3%B6teborg-... . Google Translate at https://translate.google.com/translate?sl=auto&tl=en&u=https... .
You can see the changes are in the "sharpness" of the recommendations, and in case of a local outbreak. For example, from "you shouldn't take public transport unless you can book a seat" changes to "you shouldn't take public transport."
But it's still as voluntary as it was a few weeks ago, so if we were "no-lockdown" then we'll still be "no-lockdown" tomorrow.
