Thanks for the feedback. Our target customer is a team of developers and content creators that have experienced the pain of building and maintaining an installed CMS (could be any number of installed CMS systems WP being the most popular). If you haven't experienced that pain / are ok with it as a trade-off, that's fine. You're probably not a customer.
And I spent years building WP websites, made a career out of it for a while, so it's not anything against WP and certainly don't intend to come across the way you described. So really Cosmic JS was built to satisfy my own needs that I didn't get from an installed CMS.
