I am reading it as "we don't any any option outside China and we have to live with this". I guess even after adding cost of doing additional of products you buy from China its less than what you would pay to buy it from other place.

Thinking about it more, what you are doing make sense also because tampering can happen with any supplier, irrespective of factory location, given how aggressively states are pushing for spying on each other and their people.
