Because US is not really a free country.
It is obviously way better on this matter than China, but in principle, liberties are selectively granted in US and in China.
The TikTok ban topic has been stale for long time before it became the main harbor for Pro-Palestine content after it became under censorship by US social media thus depriving anti-Palestine from controling the narrative, effectively becoming a major concern for AIPAC et al.
Data collection is more of a plausible pretext at this point.
Every country has "selective liberties", that is not a very meaningful criterion.
