Do you actually, bottom-of-your-heart believe that ordinary consumers think like this? They use TikTok and WhatsApp and Facebook and the Wal-Mart coupon app as a product of deep consideration on the web of trust they're building?
Users don't have a choice, and they don't care. Bitlocker is cracked by the feds, iOS and Android devices can get unlocked or hacked with commercially-available grey-market exploits. Push Notifications are bugged, apparently. Your logic hinges on an idyllic philosophy that doesn't even exist in security focused communities.
Yes, I do believe from the bottom of my heart the users trust the operating systems they use. Apple and Google have done a great job at security and privacy which is why it seems like users don't care. It's like complaining why you have a system administrator if the servers are never down. When things are run well the average person seems ignorant of the problems.
