IDG Contributor Network: Can Collabora and Nextcloud crack Office 365 dominance?

Newly formed Nextcloud and Collabora Productivity have partnered to bring  Collabora Online Development Edition (CODE) to Nextcloud users. CODE is the development version of Collabora Online, an online version of LibreOffice for enterprise customers.
While Collabora Online offers an open source alternative to Google Docs and Microsoft Office 365, when I played with it I found it much closer to LibreOffice and Office 365 than Google Docs as it offers full fledged office suite capabilities.
