Earlier quoted context omitted.
Static site generators are an interesting case, which can go either way. Because the site is static, but the creator still wants to be interactive, you tend to get a lot of JavaScript dependencies that fire off a bunch of 3rd party requests instead. Form handling, comments, user profiles and the like, along with the usual analytics and ads. The resulting mess can be much heavier.
That's a good point, although there are many static site generator and theme combinations that don't have that problem, either by not being interactive or by limiting the interactivity to when the creator is editing locally.
I'm seeing both cultures, and hoping that the lighter wins.
But the dichotomy is a interesting statement on how the wider public thinks.
