Websites try to aggressively optimize your content for lower bandwidth, so they compress it using lossy algorithms.
Ad networks want to represent the ad content clearly so they are not as aggressive about it.
The irony is sites who care that much about performance kill their own performance by adding these slow ad networks. It’s wild how much ads ruin your load times.
And burn through your data cap if you're poor and/or on a mobile device.
I always use VPN connected to my home network on my mobile device. This allows me to enjoy my PiHole even when not home. Though IPSet adds overhead for the network traffic, I like thinking that this setup uses less data in total due to not loading ads.
They don't care about performance, they care about cost.
There are two different customers here. The site wants to serve the absolute minimum required resolution they can get away with before the user goes somewhere else. This saves money on bandwidth and storage. The ad networks customers are the advertisers and they want their ad to be high quality and presented quickly so it's harder for the network to trim the fat.
There’s only one customer (and you’re not it).
Eh you can pay for YouTube or Netflix. They'll still try to serve you shit quality and ads If they can get away it. It might be 4k but it's probably at the lowest bit rate they can get away with while your device which is " powered by AI" makes up some shit to fill in the blanks.
Everyone wins!
Ads are also heavily localized, so their servers are usually close to you.
