The CCP high officials don't really care about anyone but their own relatives and cronies, while your assumption is mostly right as in the cases like Alibaba and Tencent, ByteDance isn't exactly like them, it has a kind of autonomy and internationalization those companies wouldn't dare to dream of. ByteDance isn't as beholden to the party as those two since it's a startup capitalized on the app economy, it's growth is organic, didn't rely on government policies and protection.

In fact ByteDance already has blockbuster app killed by Chinese authorities.
