> you must retain the original Product logo when distributing the program
I understand "retain" in the way that you have to display the logo anywhere where the original OnlyOffice displays it. So I think you actually have to "use the branding of OnlyOffice".

Did they? If including the logo anywhere counts as attribution, I don't think they did. The logo is still present in several places:
AGPL allows for compatibility with a requirement for attribution but it doesn’t not allow (and explicitly says people can ignore) any further requirements beyond that.
A copyright attribution is e.g: “Copyright 2026 kube-system”. Attribution does not mean the same thing as “logo” or “branding”
The OnlyOffice license is ultimately a terrible crayon license. Those two requirements they wrote in are self contradictory… in consecutive sentences even. I kind of doubt that any court is gonna take that super seriously. It seems to be intentionally misleading or malicious, which is frowned upon.
I agree with the posters above that OnlyOffice conflates retaining branding with retaining attribution.
However, AGPL doesn't require retaining attributions other than copyright notices by default. Under section 7b, the copyright holder can specify which attributions to retain.
Under 7b, OnlyOffice specified that forks must "retain the original Product logo". I agree with others that this is not a legitimate way to request attribution, and therefore this could be removed from the license. See section 7:
>If 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.
Therefore, I think there is no obligation to attribute OnlyOffice, only to retain the original copyright notices.

Additionally, I haven't seen any evidence for the claim that Euro-Office actually removed the logos from their fork. Can anybody find such a commit?
It has been alleged that the company behind OnlyOffice is selling a modified version (P7/R7 Office) is Russia. These allegations aren't completely meritless.
What is the implications / meaning of that? If a software comes from a trusted source and there's adequate mechanisms to make sure file contents aren't stolen / accessed -- why be concerned with who else has the same software?
From the general user's point-of-view: Using OnlyOffice's paid products may be problematic because of sanctions against Russia.
From a contributor point-of-view: If I voluntarily contributed to OnlyOffice, I would be unhappy that the company sold my AGPL-licensed code and attempted to hide the fact. Granted, they probably require contributors to sign a CLA, so as to make this legal. And yes, it is also unclear if P7 was a single-time fork of OnlyOffice, or if it continually takes code from OnlyOffice.
From a random Russian person's point of view, it would be very unfair to learn that the (ostensibly Russian) software you have bought (because P7 appears to be solely commercial, not freemium, but correct me if I'm wrong) is in fact open-source and gratis in the West.
On the one hand, the authors of AGPL certainly didn't intend the "Additional Terms" to be a means to restrict forking. On the other hand, Ascensio System SIA apparently wants to restrict forking, and flouting this is asking for legal trouble (especially since Euro-Office appears to be a major thing).
