Thanks, that’s very specific and actually happened.

Good point

Which elections would those be, in which country, and which candidate benefited?

Look up Cambridge Analytics and the Trump campaign in 2016.

I think you missed the firmware update from 2020 when we decided American elections are not rigged.

This isn’t about rigging elections. Nobody thought the 2016 election was rigged. What happened was hyper specific advertising profiles for voters, generated from all the info on Facebook, were used to customize person-specific political campaigns. If you were in a key swing district, you would’ve got nonstop ads for Trump that told you he was going to do X, Y, and Z, where those happened to be the exact three political issues you cared most about. It is widely believed in political science circles to have been what led to the surprise Trump victory.

This isn’t rigging an election because real votes were cast and counted. However is it still a fair election if the electorate doesn’t have access to sufficient information so as to make an informed choice? That is the issue at stake here.
