> most people's network use is not tampered with in a way that directly interferes with their enjoyment most of the time. If that's really all you wanted then you can reason TLS is unnecessary for you I would go beyond that and say that the reason most networks people use do not tamper with the traffic is because most people use TLS nowadays. Not too long ago, it was very common for networks to use a "transparent HTTP proxy", intercepting all TCP port 80 traffic and redirecting it to a separate box with a caching HTTP proxy like Squid, in an attempt to reduce the traffic. This sucked whenever the HTTP proxy misbehaved (which was not uncommon; many operators seemed to configure it to cache more than it should). Since nowadays most HTTP traffic is protected by TLS, transparent caching HTTP proxies no longer provide a relevant reduction in the bandwidth use, and so they became less common.
