Unfortunately, MITM is also possible for SSL and SSH (
http://en.wikipedia.org/wiki/Man-in-the-middle_attack#Implementations lists
publicly available implementations to execute them!).

To mitigate the attack, basically the only option listed at
that's available to us, hasn't been implemented (yet) by most large parties
either (definitely not GitHub or Google): it's the roll-out of DNSSEC.

Well, lets start with just implementing SSL certs to improve the situation.
Then, from there, we can work to implement the rest. I'm mainly writing
that the attack exists so that you're very careful when you trust the
"green lock" when dealing with your bank's internet access methods.
