The fact that there is any pressure whatsoever. Of all the countries in the world, China is the most able (from an economic and political standpoint) to tell a western company to take their service and shove it.
That's a very shallow view of how the non-autarkic part of the world (to which China certainly belongs) works, China's recent history and the influence of the "cocacolonization" effect. Stating it exerts no pressure whatsoever is an extraordinary claim.
