This is down to no-one caring about speed for brochure websites. The client just wants their website up as cheaply as possible as quickly as possible. The quickest, cheapest way of building a brochure site is usually Wordpress using a off-the-shelf template. And no-one in that entire chain cares about the loading speed of the site. Also, I'm not sure who the article is aimed at? Local lawyers are not going to read this and be able to fix their site. The owner of the web design agency that they bought the site from isn't going to read it because they moved from tech to biz. The web dev who is implementing the site already knows this, but has to knock out sites as quickly and cheaply as possible, and so this isn't something that matters.
