I personally couldn't care less if TikTok is banned or not, but you have to be naive to think those big tech companies are not involved in the same activities, especially after PRISM.
PRISM was done under warrants or on non-citizens, and never with the consent of the companies involved, so no they're not involved in anything resembling the same way, as far as we know (unless you have specific new information to share from a credible source).
