Arguably, that creates a more user-hostile internet browsing experience compared to just allowing for those in-page modal pop ups. At least with those they're few and far between and you can just close the tab and forget about the site.
I don't think "hostile" is the correct word, since it improves my browsing experience. It does more than stop modals -- it prevents 90% of the design, advertising, and tracking garbage on the Web, and I can now read websites the way I want.
