E2e encryption to prevent that peaking didn't really debut until the 2000's, as that's right when the crypto wars ended. Spam was actively fought in 1990's, and then improved measurably into 2000. See projects like Hashcash in 1997, anti-spam tool. So your premise doensn't make sense with that timeline. Right when consumer privacy measurably improved via encryption availability and the end of related legal challenges is right around the time spam improved as well. Which is to say, there is no correlation that's logical b/t the two in my mind, but if anything the timeline invalidates privacy improvements -> worsening spam without more evidence.
