Did you know that when you use the Share button on YouTube to share a video, that it has tracking embedded in the link?
This type of tracking allows google to "link" your socials together to your YouTube account to better profile you.
If you don't want that, always be sure to remove the "si=long string of text" from the link before opening it.
Save yourself some worry.
You can also paste the link into https://invidi.link and hit "Go random" and those sites don't have tracking at all, ever. Nor do they have ads!
