I think having a small "Dismiss" link or "X" button could feel a little less coercive. I do appreciate being able to click outside the modal to do this, but it wasn't immediately clear at first.
Clicking outside of the modal doesn't really dismiss it? It just puts it at the bottom of the page.
Thanks for that hint! I was already prepared to close the tab because I didn't realize I could dismiss the popup. I guess the main reason for that is because it's early in the morning where I live, but also, nowadays when you get a popup like that (e.g. on Twitter or on paywalled sites) and it doesn't have a "close" button, it really means "log in, sign up or §$%& off"...
