They built a kanban board and a collaborative notes application. There is nothing wrong about that.
Quite the contrary: Project and knowledge management or so important that you should not have just one (and additionally closed-source) application for that.
It's good to have competitors who focus on different workflows (Evernote was not built to be collaborative, Trello does not offer other display modes such as cards and a basic calendar).
I would not complain if they created another CRM as simple as Highrise or an open source helpdesk that could replace Zendesk (I really like helpful.io for this, btw).
