I went with this JavaScript:

    let c;
    for (let p of document.querySelectorAll('body>p, body>div')) {
      if (p.classList.contains('aside')) { c = undefined; continue; }
      p.querySelector('span.time').remove();
      if (c) {
        c.innerHTML += ' ' + p.innerHTML; p.remove();
      } else { c = p; }
    }

And this CSS:

    body p { width: 100%; }
    body div.aside { width: 100%; border: 1px solid black; }

I'm thinking maybe that page was supposed to be embedded somewhere, next to a video maybe? It wasn't meant to be read like this right?
