Schrems I was 2013, which you'll note is 3 years before the US 2016 election and the covid-19 pandemic which are the two factors that really raised the tempo around the misinformation discussion. It's also 3 years before GDPR was passed, relying on earlier european privacy law and being largely driven by private citizen campaigns (including Europe vs Facebook).

So while the contemporary US discussion is far more dominated by elderly consuming political content, that doesn't mean nobody cared about privacy. You just need to see the furor about Cambridge Analytica or the Snowden leaks to see that that is a concern.
