Professional journalists write like this, because journalism is intended to be consumed "statelessly"—i.e. with no assumption of previous knowledge.

Writers for "progress announcements" blogs like this one, don't tend to write in this style, because these writers know that the only interest anyone would have in a such a blog is if they already knew what the subject was and then wanted to subscribe for updates.

Which is to say, deep-linking to a progress-announcement blog from another website is basically almost always entirely useless, and the webmasters of such blogs would actually do well to disable it entirely (e.g. with a robots.txt policy + a server-side hotlink-detection redirection rule) and just suggest that people interested in sharing the announcement, should instead write a few lines of "actual journalism" on their own blog about the release, and then share that.

People who like linking directly to primary sources would hate this, but sometimes primary sources are not in the easily-consumed essay or encyclopedia-article styles that much of the modern web has become. Sometimes a primary source is just a commit log, or a diary, where you need to "go back" to get any context. The primary source gets to do what it likes; it's not beholden to the Internet. If someone wants a good summary to share, they're beholden to write one.
