I'm not sure how many times this needs to be explained:
Whether or not you agree with their decision to do so, Riot's plan is to replace the lore displayed in-game with these short-form summaries while keeping the full-length pieces available on the website. Some tech problems have apparently been keeping them from fully committing to this approach, with the same piece appearing in both places, but they tell us that they have no plans to do away with the traditional bios. We're stuck in this awkward middle-ground wherein the guys at Riot have fallen horribly behind schedule and thus can only show us half-baked ideas rather than their true intentions
I realise it's been a full month since the Shurima update went live, but the lore team still need more time to get their act together and properly lay their cards on the table; we haven't seen everything they wanted to launch alongside Azir, and that includes the full-length bios for characters like Skarner and Rammus. It's a pretty damning indictment that they still haven't solved these problems thirty days down the line, but no amount of negative press and hyperbole on our end is going to resolve their tech problems and get the full bios on the site any sooner.
All we can do is wait and hope that they'll be with us soon(tm).
