I don't know why many people repeat a bad idea again and again

Why all want to build such a CMS which is old-fashioned (Wordpress-style)

Please check Bubble.io and if you find its atomic design approach awesome come back to me if you want to build the next Unicorn startup

Tina and Bubble.io have no overlap in terms of intended market. And Tina isn't even remotely 'Wordpress-style'. The idea is that you -- a developer -- already have a beautifully coded, optimized website/webapp. All you want to do is provide an interface so non-devs can edit content, and that's what Tina provides. It's an open source toolkit for providing an editing UI. It's not a CMS or 'walled garden' tool that you build your site/app inside, nor is it yet another wordpress clone.
