On Android it’s simple, patched with YouTube ReVanced Manager

I did, but after the 3 videos, it’s no longer a pop-up that can be removed, it doesn’t load the video at all. Annoying as fuck. I use incognito mode as a workaround currently.

Similar there was another hack where a site would have a visible input for like email, and you could choose auto complete to fill it in, then there were hidden fields for all the other info that could be auto completed that the site would unknowingly take from the user too, also fixed, but I found it interesting when I heard about it.

Sigh, I only scrolled like a page and then realized this post is 2 years old. Wish more people would migrate

It’s actually for security. Otherwise websites could grab whatever you happen to have in your clipboard. You might have a copied password from a password manager, or a private key for a wallet. I don’t want sites having defacto access to the clipboard for that reason.
