Yeah, I agree that the major concern here is not the platform itself, but the very real security concerns around the parent company's relationship with the Chinese Communist Party.
Other companies whose parent companies have similar links include
- Huawei - hence the ban of their equipment in US, Canada, and other regions
- Discord - although I still use it
- Epic Games/Unreal
- Alibaba - obviously
I think that honestly, it is scary enough how much data US companies gather on us. If you use the DuckDuckGo browser on an Android device, it has an optional feature to block 3rd party data transfer from apps. I've seen GPS data, screen resolution, OS version, screen gestures, browsing data, and many, many other data points being captured by Google, Facebook, Salesforce, and other 3rd party advertising companies. That data is used to target communications.
Now imagine that indirectly, the Chinese Communist Party, which has interfered with elections using ads and fake groups in the past, just like Russia, has access to that same data for MILLIONS if not BILLIONS of people. The scariest thing is, almost every country is doing this, including ours. It is a very scary idea that China could target specific disinformation campaigns or get access to private communications between government officials etc.
The internet is an amazing tool that has revolutionized our world. The only problem is, the concept of privacy has not evolved with it in as meaningful of a way. Hell, governments don't even need to keep tabs on us and spy on us anymore. They can literally just BUY the data from Google, Facebook, and other 3rd party advertisers. The difference in China's case is that they have companies that are legitimate companies who are in their pocket and DIRECTLY send them the data due to the government's sponsorship of those companies.
