I don't know, but does it matter really? If somebody can access it, 
he/she can also learn whatever protocol that is.

Isn't it Google's responsibility then to assess the risk if it wants to 
use 1K keys? So where exactly do you want to draw the line?

If it's Google you don't agree but if it's Visa you agree? And if it's a 
user using some outdated router do you agree too? Maybe only for Alexa 
top 100 host names? Else?

Probably - but their offense was first of all that they issued 512 bit 
keys (which might not be such a bad thing after all following your 
logic). Then they were non-revokable. You can find such non-revokable 
certificates [*] also from other CAs apparently. And then one might ask 
if we need any rules at all...
