Yeah I had to implement this once because we ran a handful of ads on TikTok, so they wanted access to all of our traffic. I protested, saying they didn't need all traffic to do analytics for people who click through.. just tell me how to identify the traffic you need. This is fair, if somebody clicks on an ad then analytics would be expected. Yeah no, they didn't allow their advertisers to do that. I ended up getting permission to remove from the site when their pixel was found to be causing a performance impact for users. But without good monitoring for that they would have still been running, possibly for forever. I'm sure this is basically how they get to be everywhere.
