The movement to encrypt the web reached milestone after milestone in 2017. The web is in the middle of a massive change from non-secure HTTP to the more secure, encrypted HTTPS protocol. All web servers use one of these two protocols to get web pages from the server to your browser. HTTP has serious problems that make it vulnerable to eavesdropping and content hijacking. By adding Transport Layer Security (or TLS, a prior version of which was known as Secure Sockets Layer or SSL) HTTPS fixes most of these problems. That’s why EFF, and many like-minded supporters, have been pushing for web sites to adopt HTTPS by default.
