Every user is different. But software developers commenting on HN like to assume one size fits all. Perhaps this makes sense if they are getting paid from advertising. If every user is doing something different instead of all looking at the same website, using the same app, watching the same video, repeating the same meme, using the same few browsers on the same few operating systems, etc., then advertisers are less interested in throwing money away on "advertising services" from so-called "tech" companies.
