Apple last quarter generated 16% of their revenue in China. They've also cooperated with the HK/Chinese governments to pull police tracking apps[1] and VPN apps[2] from the App Store.

I'd say even if they relocate 100% of their manufacturing from China, they'd still stay silent because 10B of revenue per quarter is very significant to their top line.
