That's not entirely accurate - TikTok does have a JS "pixel" implementation that website owners put on their site, mainly to track conversions. It's true that the use case makes it less popular than a like / share button. I research these JS snippets and how they work, and I can say that without a doubt the TikTok pixel is the most complex and network intensive one. It without doubt collects a lot of information. As more advertisers move to TikTok, i see this pixel implemented in more and more websites.
Tiktok only competes on user interests within their app but can’t collect user profiles elsewhere. In terms of privacy, they’re harmless compared to FB/Google/Twitter.
