Yes. Of course terrible things do happen in China. But the assumption that Google's product will cause this to happen is currently just someone's imagination.

The product hasn't launched yet, might not ever launch, and we don't know how the product will work if it did launch. I'd hope they're thinking about how to make sure nobody gets in trouble, but we currently don't know what precautions they came up with.

There are lots of companies working in China. We know of one incident involving Yahoo. Do we assume without evidence that any other companies working there have caused dissidents to be tortured?
