Yes, but remote activation pretty much means targeted. I am absolutely convinced that there are backdoors in huawei devices, be it intentionally or through carelessness. There's news about backdoors in Cisco products at least once a year - completely accidentally obviously, since we are the good guys. However, the Chinese would be very careful about using them. Every time you do, you risk getting caught, because just in that moment someone on the target network could be running wireshark to debug some unrelated problem. And once you're caught you're done. You won't risk that to fetch some random HN user's browsing history to blackmail them.
