I don’t know about the US, I live in the UK which reports all testing including the at home self reported LF test results. I don’t think that our world in data being a rubbish data source on its own is a new thing (any data source is rubbish without context), even in the beginning of the pandemic you had major discrepancies. Perhaps other than for a short time when everyone was basically doing mass testing during the initial lockdown period around mid 2020 but pretty much since then and especially since the vaccine was rolled out every country has been doing their own thing. Just to put things into perspective for the past month the UK averaged about 900K tests per day, Sweden averaged about 15,000… even if you account for Sweden having about 6.5 times fewer people it’s still a drastic difference. And whilst not everyone went as nuts as the UK, Italy is still doing about half a million tests a day. https://ourworldindata.org/grapher/full-list-covid-19-tests-per-day?time=2021-10-19..latest&country=GBR~BEL~DNK~FRA~IRL~ITA~SWE https://ourworldindata.org/grapher/full-list-covid-19-tests-...
