There is no violation of policy when both sides of the strait have differing views on what "one China" means. China can warn all it wants. It has been threatening Taiwan for decades. Frankly, Taiwan and the rest of Asia have had enough of China's arrogance.
I would add that recognition of the "One China" policy is just lip service for trade. Talk privately with any politician or leader of industry and they'll admit as much. Another way to view it is that it's merely acknowledgement of what China believes, the same strategy you might employ dealing with a petulant toddler.

Living in East Asia this is something I've observed when the subject comes up with locals. You're also going to hear similar if you watch the local news. It's certainly not an "anti-China" bias limited to the west.
