The reason US and vassals want to ban TikTok and Wechat and even Telegram is because in the era of QR codes and digital virtual money etc, China could easily incorporate the e-Yuan on these apps and use these applications as a platform to challenge the US dollar hegemony directly...
US will likely soon force Google and Apple to not only delist all Chinese apps from the app store but to force uninstall/remove existing ones from the entire install base of billions of users/phones worldwide (not just in US, 5eyes, west etc) and all the major telecomms to block traffic to these application ip addresses and domains and servers and hijack/redirect root dns tld to block these apps (like what happened to KimDotComs megaupload.com )....
Most of the VPNs are actually gov honeypots and all will bend to political pressure, heck ProtonVPNs CEO a while back send emails and made blogposts to ask its users to proactively delete wechat and tiktok from their phones!!!
