Brave and Firefox have a feature to remove this. LOTS of sites track like this, not just Youtube. Get in the habit of copying clean links!
yeah you just have to remove everything after the ? and it will work just fine
Not everything after the ? those parameters also contain the playlist and starting timestamp for example, so you might want to keep those. As the post above says, delete the “si=…” up to the next & or the end of the url, whichever is first
This isn’t just youtube btw. Anything after ? in a url is additional info that’s passed to the web site and can be anything from the page number of a large collection to tracking data.
Sometimes the key name is obvious, like sort=ascending, or page=4. Often though, especially if the programmers don’t want it to be obvious that it’s for advertising or identification purposes, they’ll call it by a single letter or abbreviation. Generally any value that’s a long jumble of text/numbers is used for tracking purposes because it needs to be unique. It can (and should!) be deleted when sharing links.
Also, if you are copying and pasting a tumblr link and can take the time to delete the ?source=share from the end, please do, as it seems to make the link behave much better and avoid some of that “open in app” or “behaving like you aren’t logged in” nonsense.
