When you share a YouTube video using the share button it adds “si=some_unique_code” to the URL. If you don’t remove that it shows your personal account to anyone who receives it so that they can chat directly with you. For a lot of people this is their real name.
I’ve seen it all over Lemmy so I figured I’d mention it here! You only need the stuff before the question mark in the URL to let others see the video.
This can also be turned off in your YouTube settings under the privacy section. The setting is “channel visibility for shared links”. It will still add the si code for tracking though.
I don’t see how it’s a generational thing. I remember when every link included the page type at the end, meaning there was nothing that could be truncated. If you don’t know what si stands for or don’t know that anything after a ? Is tracking bullshit, then you simply don’t know. It’s a “knowledgeable person” thing that can be learned at any time. I’ve pointed it out and many people I know still don’t care
People who grew up when smartphones were already a thing might never have needed to learn how the Internet and URLs actually work. To a lot of everyday users nowadays, the Internet is just a series of smartphone or tablet apps you switch between. I used to think that the spread of the Internet into more segments of society would create a society of computer nerds, ha ha ha ha ha nope.
As a web developer, everything after the ? is actually parameters for the request. Anything could be in there, even important stuff (though hopefully nothing identifying, since that is extremely unsecure). You will likely break functionality if you delete everything without knowing what it is.
People can’t even unanimously agree on when each generation starts and ends (see terms like “zillenial” or “xillenial”) so I’d even go so far as to say it’s a completely redundant concept in the colloquial sense. Obviously most people care more about continuing to use the “kids these days” rhetoric so it hardly matters regardless, but it doesn’t make it any less ridiculous.
