I do love thinking about all the tree shaking, minifiying and bundling that went into slimming down a website as my browser struggles to decode a few MB of json and makes 20 async calls before fully rendering the screen.
Unless the requests are triggered after another request finished of course. That's still significantly impacting loading times
When work depends on those resources it can't even start until all the data is returned. Far too often nothing can happen until a case are of resources gets returned. Then there's the fun outlier of some slow AdTech script that finally returns, screws with the DOM, and causes a layout and repaint.
It's just today's "What Andy Giveth, Bill Taketh". Great job all around everyone.
why is everything so terrible to use then :-(
Most sites load pretty quickly with ads blocked, even complicated over-engineered SPAs.
More and more web sites stall, or refuse to load at all with ad blockers enabled. Even ad-free ones like government web sites, because they use the same tracking mechanisms.
Though you are right, it does happen. If Google's tracking code doesn't load you can't buy tickets on Northern Rail's¹ site for instance.

I know that circa 2018 the ad industry suffered a shock as major players started measuring more precisely what value ads brought, and CPC went down, I think things just got worse at this point because websites crammed more ads in response.
You should not have to look this one up: xkcd 624.
Then one day a new prisoner arrives.
Later that day when everybody is at their cells some other guy yells: "194". And,as usual, all people laugh.
Another one says "315". Even more laughter. Another: "873", the place is a mad house.
Emboldened and wishing to fit in, the new guy yells: "242".
Total silence. Not even a little chuckle. Embarrassed the new guy turns toward his cellmate and asks him: "What did I do wrong?,Isnt 242 a good joke?". His cellmate says: " it is indeed a good joke, it is hilarious.But you see, son, a joke is not just the story, the most important part is the way you tell it"
