The title should be changed to "PinePhone KDE Community Edition is now available"; the article is about PinePhone, not KDE.
I'd say it's "confusing" rather than "misleading"; this is because of lack of context. Reading "KDE Community Edition released" when you're on a Pinephone website is more meaningful than reading "KDE Community Edition released" on Hacker News, with only the pine64.org domain being available next to the link.
