Because writing is, in many senses, exposing yourself, and at the very least you want the recognition for it (even if only in the form of a visit to the website, and maybe the interactions that can follow)? Maybe you want at least the prestige that comes with writing good content that took a lot of time to create. Maybe because you want to participate in a community with your stuff. Maybe other million reasons.
I know that medium, substack and the other "publication" platforms (like LinkedIn) are trying to commodify even the act of writing into purely a form or marketing (either for a product, or for your personal brand), but not everyone gave up just yet.
