The web is chock full of shit JavaScript; most of which is not adding value for me (ad placement, etc) and some of which is at odds with my interests (trackers, etc).
We have every single web site wanting to give me some sort of unique experience when all I want is to navigate to the information I want and maybe buy something.
I think that the web is insane. I want the web to deliver content and I want my client to present it to me in a way I control. Instead, every server wants to control my browser so they can control my experience and extract data from me.
It messed up.
