Through all of our technical advancement, hosting is still expensive, okay? /s
People act like we couldn't afford to host things in the 90s before Moore's law ran for decades. Suggesting we wouldn't have blogs/websites if not for advertising
My guess would be the person running the website has used one simple 3rd party include that then loads all of the other things so that they might not actually be aware of what's being done under the hood. Or, they are a sociopath. But not being able to come up with reasons is not a good look.
