On: TLS Everywhere, not https: URIs (2015)

[vtsingaras]

The problem with opportunistic TLS is that while it protects from wide-scale DPI it doesn't protect against MITM. Personally I think that the effort that would be put to implementing opportunistic TLS in all web servers and browsers would be better put to migrating all web applications to HTTPS only.

Agreed, and MitM is arguably a bigger threat than DPI to most people, especially if you use coffee shop wifi, etc.
