谷歌拟标记所有HTTP网站为不安全，纯静态无交互HTTP网站为何仍不安全？

Great question—this is a common point of confusion for folks running super simple static sites. Let’s break down why Google flags even these minimal HTTP sites as insecure:

• HTTP is unencrypted by default—full stop
  Every bit of data sent between a user’s browser and your server over HTTP travels as plain text. That means any network intermediary (like a coffee shop router, ISP, or even a malicious actor) can easily read, modify, or inject content into that traffic—even if all you’re serving is "Hello, World!" The warning isn’t about your site’s content being dangerous; it’s about the transmission path being vulnerable.

• The warning targets the connection, not the site’s features
  Google’s "Not Secure" label doesn’t care if you have user forms, external links, or sensitive data. It’s a blanket alert about the lack of encryption in the browser-server connection. The goal is to train users to associate unencrypted connections with risk, regardless of what the site actually does.

• Google is pushing for universal HTTPS across the web
  For years, Google has been prioritizing HTTPS in search rankings and browser UX to move the entire internet to encrypted connections. Marking all HTTP sites (no matter how simple) as insecure is part of that push—it removes any ambiguity about which connections are safe to use.

• Even "harmless" content can be tampered with
  Think about it: if your HTTP site is served over an unencrypted connection, a bad actor could intercept that traffic and replace your "Hello, World!" with something malicious, or inject unwanted ads. The warning is a heads-up to users that they can’t be sure the content they’re seeing is exactly what you intended to serve.

FWIW, setting up HTTPS for a static site is way easier than it used to be—free tools make getting a certificate trivial, and most hosting platforms offer one-click HTTPS setup these days.
