Google is a search engine. Neither God nor the government of the world.

And TCP is something to exchange data with. No more, no less.

And although it's completely off topic here, I would like to state that 
in my opinion Google has by far too much influence in politics, 
administration and even science.

Anything can be changed - when there are valid reasons for doing so.

I see billions of reasons. They are called users.

And for how many RTTs aggressiveness is acceptable?

As I was told by a Telco guy, the first and main duty of a customer of 
the "Deutsche Bundespost" was not to disturb the system and not to 
disturb other customers.

In times of "social skill" and "EQ", this is sometimes referred to as 
living in a well behaved community. And in that, Google plays _one_ 
role. Like any other people in the world. Google is not alone on this

Everyone is free to do research in this field and to discuss his results 
within the community - and when changes make sense, everyone is free to 
contact the IETF and to convince them by compelling work.

However, care should be taken not to let any unrecognized genius mistake 
the world as his private playground.
