This is caused by induced demand. This comes up a lot for car traffic [0]. If you build wider roads, you will almost always just see an increase in traffic, up to the point where the roads are full again. The metaphor is not perfect, but I think it is fairly apt.
Expanding infrastructure increases what people can do, and so people do more things. In some cases, it just decreases the cost of engineering (you can use more abstractions to implement things more quickly, but at the cost of slower loading sites). But in the end, you should not expect wider pipes to improve speeds.
