I disagree. Fully justified text was the norm for narrow-column media such as newspapers and some magazines. Ragged-right was the norm for wider media such as printed books because, for physiological reasons discovered over centuries, it's easier to keep your place in long paragraphs. Most web media are narrow-column format, so tend to be fully justified. Whether that's good or not tends to be a matter of how one is consuming the matter: a high-pixel-density phone at 15 cm vs. a 1080p monitor at 45 cm call for different presentation for optimal readability.
