I don't need E2EE on my email even though I know govts and corporations are reading my email. But I also want that recruiter email or email from zoom telling me if they are going to give me discount on my next payment cycle. And most people will put zoom, steam, and any other services like bank and govt agencies in the white list. So no costs will not rise. I don't use steam so even if steam pays money to send me mail with their offers , still I will delete it and they understand that. So unless it's a recruitment offer from steam they don't need to pay money to send mail to me. So prices won't rise because corporations will only rely on customers who are white listing them. Anyone else they will not send so overall the prices will go down rather than go up. You may think but how will Steam get new customers if not flooding the planet by emails. They would turn to influencers and affiliates. Maybe they already use them.
