This website is an excellent example why I browse the web with JS off by default these days. When I turned it on, an obnoxious icon appeared, refusing to go away. When I hovered on it, another box appeared with an x in the corner. I moved the mouse to close it, and the box disappeared. The obnoxious icon, however, stays as before.
I'm really glad we are still able to turn JavaScript off these days. I'm pretty sure in the next years more and more so-called "developers" switch to text rendering by JS, rendering more websites unusable.
