Not too obvious to me unless there's some actual evidence of any of these claims of "China takes American data".

They take as much data as any of the various other manufacturing processes we outsourced over the decades.

Answering tit-for-tat is fine, even if the thing being done is bad in itself (e.g. waging war is bad, but should a country not use weapons to defend itself when invaded?). If else US and in general the West should have acted earlier: if American companies where free to operate in China and influence its people I doubt this ban would have been enacted.

I need to print this sentence out, frame it, paste it on the Tiananmen's wall.
