Is the banning of WeChat/TicTok a modern day act of war?

I have no love for the Chinese "Great Firewall" that blocks non-Chinese tech firms access to the Chinese market. Prior to 2002, I ran the largest Chinese social network from the US until one day the Chinese government blocked it and 95% of it's members were gone. The only option was to try to sell it to a Chinese competitor but, being blocked, it had no value.

While TicTok, the Chinese-backed short-video sharing community popular by young Americans, will survive as it can be sold to Microsoft/etc as most of the interactions are between fellow Americans, the US ban on WeChat is a game changer as it severs communication BETWEEN countries.

WeChat is a messaging app used almost exclusively by people outside of China (both Chinese diaspora and locals) to communicate with friends and business connections in China. Yes, China had already blocked all US-based social networks so there's parity but now such communication is pushed back to the last millennium - email and phone calls.

As someone who has friends who exclusively use WeChat, I feel the panic as people scramble to find alternatives. This executive order will have a chilling impact far more than most people think. Is it a modern day act of war?
