Why? We're discussing long-term changes to how HTTP without encryption should be handled. I think an upcoming project with major impact on the availability of certificates should be a factor in this discussion. Besides, it's not like letsencrypt will be the first CA to offer free certificates - StartSSL has been doing it for years, although letsencrypt obviously has a different approach.

Because Let's Encrypt might solve this well, or it might not solve it well, or it might never even be released. At the moment, factual statements about what effect Let's Encrypt will have on the world are similar to "$(THIS_YEAR+1) will be the year of Linux on the desktop."
