I have no problem with tech sharing in principle. I don't consider it cheating or gamey or unbelievable. It's just boring.
It speeds the game up to the inevitable end game too fast IMHO. But then some people like that.
In my ideal universe noone would trade tech, and that is why we pressed Malfador for the option to disallow it at game setup. So that it can be disabled.
I prefer that the results of the game depend on my own strategy and tactics, not of the neighbors that I happen to start next to. If you happen to be starting next to Dogscoff who loves to trade tech you are going to have a huge advantage over the guy who happens to start next to me. You and the other guy could be completely equal in skill, and even in the political side of it, but if you are next to a old fuddy duddy like me that doesn't want to trade you won't be able to until you meet some others.
