How annoying, I thought the age of obnoxious pop up ads was behind us, but they have reappeared in a big way. I fail to understand the reasoning behind why designers would want them.
I don't think designers want them. The data probably shows that it increases conversions or whatever metric, so the product owners and business pushes the designers to jam in the dark ux patterns.
And they're infuriatingly hard to block as well. But I suppose a single conversion is worth 10,000 annoyed visitors.
Unfortunately, it's because they still work. The designer may not want them, but the marketers do.
