It strips query params used for tracking. Has it never bothered you when you click share on Instagram or YouTube and it inserts a unique-to-you "share ID" in the URL? I was burned by this once, now every time I copy a share URL from a social media platform I first paste it into my text editor and remove all of the privacy invasive tracking cruft.

As an aside I think it's only matter of time before this is done without query params and instead each share link is generated just for you.
