I wouldn't say that is a weakness, you want your webpages to be as small as possible.
Websites have scripts, images, videos, ads, text. Image + thumbnail = 1MB, gallery of images = 15MB, 600 posts with images, thumbnails, comments with avatars = ... ?
My wordpress blog started in 2010 with images, thumbnails is 5GB, last time I checked in July.
This is not all on ONE page

Again, that is the size of your database, not webpage.
It is wasteful to ask leading questions, and it pollutes the discussion here. HN reacts negatively to "reddit" like comments, so I see little reason why we can't start reacting negatively to people who ask leading questions that are actually veiled blaming statements. It increases the trust of the comments and decreases the extra workloads having to parse people's illogical comments.
