"the steward of the GNU family of General Public Licenses"
It doesn't matter that they are "steward" of other licenses, the only license that matters is the one for the project. Is the FSF granted a right to declare what the OnlyOffice license says?
"attempt to impose an additional restriction on the AGPLv3"
OnlyOffice gets to choose the license, not FSF.
""inconsistent with the freedoms granted by the license"
the only license that matters is the OpenOffice license, does FSF think the license is inconsistent with itself?
"The (A)GPLv3 makes it clear that it permits all licensees to remove any additional terms that are "further restrictions" under the (A)GPLv3."
It only matters what the OpenOffice license says.
"[i]f the Program as you received it, or any part of it, contains a notice stating that it is governed by this License along with a term that is a further restriction, you may remove that term".
Does it though? And can it? Did FSF cite any evidence that such a notice is contained? Seems like that might be important.
"Confusing users by attaching further restrictions to any of the FSF's family of GNU General Public Licenses is not in line with free software."
It's not an "FSF family of ... licenses", it's the OpenOffice license. It is typical of an RMS effort to claim ownership of other people's work just as he claimed the right to name Linux. Software comes with a license, FSF doesn't get to say what that license is after the fact, particularly when it is not their software.
"However, if the decision goes against us, we are ready to consider other options."
You'd think the industry would have figured out by now to consider other options.

No mention of the product being licensed under (A)GPLv3 ever, and current license is Apache. Older versions used LGPL. As usual, it seems nothing in the summary can be trusted, as is the standard for EditorDavid.
