well, they took a position on a hypothesis that failed (natural herd immunity), and have now corrected. Proving a hypothesis wrong is part of the scientific method. Shame about the lives lost though, but at least they've remained objective and to a casual observer apolitical. Luckily Sweden's demographics and health care system did not resemble those of other "embrace herd immunity" states such as Brazil or India.
India had a very tough lockdown last year, which did tremendous harm.
