I also think there’s something weird going on with YouTube recommendations. The thing that I’ve noticed is that people I follow on TikTok are showing up in my YouTube recommendations, and I’ve never interacted with their YouTube accounts. Most times I didn’t even know they had a YouTube account.

I use the same email address on both accounts, but it seems weird that TT would export its follow graph to YT for any reason.

How is that surprising? Maybe you just get recommended the same stuff on multiple platforms because it reflects your interests? If I am interested in Retro computing and get the 8-Bit Guy in my recommendations on multiple platforms, would you conclude that the platforms colluded? Occams Razor tells me what’s the more likely conclusion

Because I have never interacted with any of that type of content or creators on the platform, and then when I suddenly get 10 different creators recommended to me simultaneously from 10 different topics. That’s weird.

I also explicitly said it would be “weird” for them share information, so you concluding that that I think collusion is the result is unwarranted. Perhaps you should work on your reading skills instead of injecting your assumptions.

Are Google's cookies / ads / analytics used by TikTok? Does TikTok send notifications to your email address (is it Gmail?)? Do the TikTok accounts embed YouTube / related links in their profile anywhere? Quite easy for Google to get tracking info. So many ways that metadata gets leaked.

Maybe Google are listening to you use Tiktok?

I would prefer a more plausible guess
