For example, the article mentions government recommended mask wearing and that it took until December for the recommendation to be put forward but you need to understand the details to fully realize how ludicrous its implementation is.
First of all, it is not mandated by law but only a recommendation which means that there are no legal consequences for transgressors.
Secondly, the recommendation only covers public transportation in select cities during rush hour and weekdays, making it difficult to keep track of when to wear a mask.
Thirdly, travelers who aren't wearing a mask cannot be removed for the premises by bus drivers, safety staff or other staff as this is a right only excecised by the police. So basically it took the government almost a year to suggest the public to wear masks but the recommendation is toothless and confusing, leading to very few people wearing masks when in public.
Now imagine the same incompetence being applied to every aspect of Sweden's Corona handling and you might understand why Sweden's strategy had been so consistently terrible.
