No disagreement about memory usage, except to say that [some web sites] are usually either poorly or unethically coded. I was on theverge.com yesterday, wondering why the network indicator was going crazy on a blog post. Pull up dev tools and it's ad code downloading megs worth of data, endlessly. Whether that's on theverge, or bad actor for ad code; I don't know or care - but when people talk about bad websites that's usually the primary example in my experience.
