I've said this before, but it bears repeating: Moby Dick is 1.2mb uncompressed in plain-text. That's lower than the "average" news website by quite a bit--I just loaded the New York Times front page. It was 6.6mb. that's more than 5 copies of Moby Dick, solely for a gateway to the actual content that I want. A secondary reload was only 5mb. I then opened a random article. The article itself was about 1,400 words long…
I don't think thats a meaningful comparison. Moby Dick is a book, written by 1 guy and maybe an editor or two. NYT employs 1,300 people. When you read a book all you get is the text. NYT has text, images, related articles, analytics, etc. Moby Dick doesn't have to know what pages you read. NYT needs to know how long you spent, on which articles, etc. They need data to produce the product and you can only achieve that…
That's analytics. The marketing stuff that is causing the bloat isn't doing that much in comparison. Trackers are often coded very wasteful and are redundant by nature. You can have easily dozens to hundreds of them all doing the same stuff just with different APIs. It is insane and out of control and has absolutely nothing to do with gathering insights about your app and improving. It is pure external 3rd party marketing.
