Thanks! At least on Safari, you can just hit Show Reader View. That’s what I do.

However, while many sites have paywall content obscured by pop-ups, but the content is actually loaded behind, some (like the Wall Street Journal, iirc) don’t actually load the content, and so there Reader View isn’t a viable workaround, and I suspect outline.com won’t work in those case either, but I haven’t tried. I will, though.
