Seems onlyoffice is "unforkable"? It's AGPL but has extra restrictions: you're required to show their logo but they don't give out rights for others to use their logo.
Doesn't the AGPL specifically disallow that? If I understand correctly, the FSF has even directly threatened legal action against developers who add extra restrictions to the AGPL. The license text is copyrighted, does not allow modifications, and includes terms allowing the user to ignore any additional restrictions, so adding extra restrictions would seem to either be ineffective or a copyright violation.
OnlyOffice claims that additional terms fall under section 7 of AGPLv3, which explicitly allows adding such terms. I think the point of contention arises from the interpretation of section 7 and more specifically this sentence:
> When you convey a copy of a covered work, you may at your option remove any additional permissions from that copy, or from any part of it.
> In other words, AGPLv3 does not permit selective application: a recipient either accepts AGPLv3 in its entirety, including all additional conditions, or acquires no rights to use the software.
> Any removal, disregard, or unilateral “exclusion” of conditions imposed under Section 7 constitutes use beyond the scope of the granted license and therefore a breach.
That's about adding permissions -- not adding restrictions. There are a list of allowed restrictions in section 7, lettered A-F, and then the statement:
> All other non-permissive additional terms are considered "further restrictions" within the meaning of section 10. 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.
I think you're confused by the term "permissions". You can give more freedom to the license and a copier can remove them as long as it doesn't remove the freedom that are in AGPLv3. The OnlyOffice team claim comes from the next paragraph of section 7:
> Notwithstanding any other provision of this License, for material you add to a covered work, you may [...] supplement the terms of this License with terms:
> b) Requiring preservation of specified reasonable legal notices or author attributions in that material or in the Appropriate Legal Notices displayed by works containing it; or
c) Prohibiting misrepresentation of the origin of that material, or requiring that modified versions of such material be marked in reasonable ways as different from the original version; or
This is what they did and what the other part stripped from their blatant copy. So no, removing the logo or the OnlyOffice terms therefore seems forbidden by the license itself, revoking it for the other part, thus they are now making a counterfeit.
It can disallow downstream licensees from doing things with it, it can't prevent the copyright holder and licensor.

If it's a copyright violation of a copyright on the license, that has no effect on the effect of the license between the licensor and licensee, though it may result in money being owed by the licensor to the copyright holder on the license.
OTOH, I think any US court would find that a party trying to control the legal effect of licensing arrangements between third parties by leveraging a copyright on license text is, itself, a fairly strong indication that the particular use of the license text at issue is outside of the scope of copyright protection. That's not protecting expression, it is instead creating a roadblock to the freedom of contract.
from my reading, onlyoffice misread AGPL and the restrictions are not what section 7 meant; however that just means it's not really an AGPL licensed code as they are using AGPL wrong, not that NextCloud can just ignore it and treat it as AGPL.
(if OnlyOffice is really all their code and not some other re-forked AGPL code. I haven't looked.)
I was wondering about how they came to the conclusion that they violated the copyright, so I went to check if they did the AGPL[1] with some extra clauses in it. Turns out they didn't, but they did change[2] it[3] in an interesting way: All the https urls in the GNU version are http urls.
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?
Important bit of information is further down in the article: OnlyOffice is Russian. I would therefore view any collaboration as a risk. It's not adequate for strategic reasons as well as sovereignty.
An example of how european "tech" reacts to threats. 2 european open source projects in litigation with each other and one of them engineered a license to prevent an obvious feature of open source software (forking) while the other is throwing shades at opacity and geopolitical control at the first.

To me (IANAL etc) that seems questionable. But I also say that the section 7 in entirety is not particularly clear.
It says that you can add requirement of attribution but also that such additional term can be removed, so it seems rather pointless?
