As 'zokier pointed out[0], we live in the age of apps. If you're not allowed to use this tool for collaborative process, often enough you may just as well not use it at all - as moving data between apps is usually a manual process that's boring, time-consuming, and lossy. Modern apps are tools of control, not cooperation.
