The number of ads on this website is crazy. I navigated back immediately. There must be a way to place a single ad more efficiently instead of filling the site with them.
I only see two short gaps between paragraphs labelled "advertisement". I don't use an explicit ad blocker - just NoScript.
I have a personal policy of blocking JavaScript content by default, and only enabling it when I judge that it would have a clear, legitimate purpose (i.e., not "make the article content visible" or "display an image inline with text" etc.). I can't really imagine using the modern Web any other way.
Ars Technica has been on a very long, downward slope for many years. I used to be an avid reader myself, now I actively avoid any links containing their domain.
This will only continue with them and get worse, I definitely suggest diversifying your news sources away from them.
