I work in the digital advertising field and know how easy it is to target people of all political variations and dispositions on issues. This needs regulation because these tech giants continue to rake in money and don't want any push back and clearly don't care enough. Facebook lied for years about how stories and news is chosen and favored (it was dozens of contractors in a separate unmarked office facility that would yay or nay how viral news posts were) because their algorithm wasn't ready. This allowed partisan favorability based on who was clocked in. Imagine if any had malintent like Russia? This has probably been going on for years... Needs to end now!
