github.comvsnextcloud.com

Github edges out Nextcloud modestly on homepage messaging, 83 to 75. Here's where the gap comes from.

Github is clearer about what it does (100 vs 53 on clarity). Github's hero ("Search code, repositories, users, issues, pull requests...") names something concrete, while Nextcloud's ("Regain control over your data") stays abstract. Nextcloud is better at saying who it's for (ICP: 94 vs 53). Nextcloud's targeting is crystal-clear, while Github's is decent.

Github uses a "Community / Movement" positioning while Nextcloud goes with "Trust / Authority" — fundamentally different approaches to winning the same buyer.
