Sure, some do. I can't speak for them. What annoys me personally is that sometimes they seem to praise very arbitrary stylistic choices as objectively superior. I think front-end developers are more prone to fashions than other kinds of developers. The blogs seem to go through phases.
That's making a lot of assumptions. They simply might be more prone to write, read and react blog posts as a general rule. Their work is also more visible than most developers' work, being customer facing.
Gotta also keep in mind the FE landscape has radically shifted in the last 5-6 years after being almost dormant for a long while - more or less coinciding with ES2015 and the emergence of reactive frameworks ala React/Angular/Vue.
