"We really need a decent, single Office application for Linux, which has a small footprint, is fully-featured and is easy to use. If it's better than Office then people will be tempted. Right now, it's not."
There are already plenty of viable alternatives to LibreOffice for Linux out there including, but not limited to, Softmaker Office, WPS Office, FreeOfice, OnlyOffice, Zoho Office and so on.
