You are totally right, but I think the main reason for encrypting everything is just the pressure from browser developers trying to enforce this. For me, it is like someone started to imagine ALL websites being e-commerce (or similar) websites, where you have to process your private data, so encryption is needed. Like someone forgot about existence of publicly available, purely information-oriented websites, where there is nothing to encrypt... (For example, the Wikipedia link you quoted above is HTTPS. What is there on publicly available site like Wikipedia - except maybe your login credentials, if you have an account there - that needs encryption? ;)) Going back on-topic :), I think that somewhat similar situation is with use of SPF and/or DMARC. To my knowledge, SPF/DMARC was never meant for "general" use. It has been invented as a way to protect particular "sensitive" sender domains (eg. the domain from which you get e-mails from your bank) from being easily spoofed. However, "thanks" to Google and other big e-mail providers who started to enforce that EVERY email send to them must pass SPF/DMARC check - as a method of "antispam protection" (which it isn't, because spammer can have a perfectly valid SPF/DMARC setup) - people were forced to adopt it universally, whether necessary or not (which for example causes problems with mailing lists). -- Regards, Jaroslaw Rafa r...@rafa.eu.org -- "In a million years, when kids go to school, they're gonna know: once there was a Hushpuppy, and she lived with her daddy in the Bathtub."
