How and why are quite obvious. I've been one of the few, including those supposedly in the know, that has maintained this will be a long process because of the difficulty in combining two contracts, two sets of language, two cultures and have three separate sides agree to the ultimate TA.
The issue is the how the proper expectations were not set and now there seems to be work being done to try and make the concessionary language seem rosy. It is inevitable to have language that is concessionary in most negotiations. The agreed language may be better for one but that compromise may make it concessionary to the other. Let's not hide from that.
