IMO this is a great illustration of how the word "reasonable" stops the entire legal system collapsing.
The Free Software Foundation sometimes went further than the Apache Foundation with their About dialog or textual notices for end users, so they would learn about their affirmative rights. The purpose of this "prominent but reasonable" preservation requirement is to retain this end user advocacy. Specifically, the GPL copyright contains a prologue which the FSF wished to broadly distribute. This badgeware stuff is a decade old abuse of this end user advocacy strategy.
An otherwise permissive license with a prominent but symmetric end user notification might be a helpful addition to OSI license options, but care is needed so it is compatible with GPLv3, reasonable to textual or embedded environments, and precludes stupid badgeware nonsense. Standard approaches and bill of materials could improve the state of the art.

The problem here isn't the legal interpretation of the license and adding new clauses doesn't seem to do anything useful. Sneaky Company can license their software under whatever weird combination of terms they like. If they want GPL except it's proprietary then they can do that. Weird but ok. Same again if they want the license to be internally contradictory - seems stupid but they can do that too.
The actual issue is if they're trying to be deceptive by framing something as GPL licensed when in fact it is some new not-in-the-GPL-spirit license that they have developed. They should either be generally shamed or sued by whoever has copyright over the term "GPL" (pretty sure that is the FSF). That'd be ironic but there you go. Or some sort of false advertising suite.
Before they even explain what the project is or what it does, you're immediately greeted with a "Legal note". It literally takes up the whole screen. It feels like a "WARNING. Private Property. NO TRESPASSING. Violators will be prosecuted!" sign rather than an invitation to explore a supposedly "free and open-source" software project.
And then, of course, they add a "Contributors welcome!" section. Sure. They're happy to accept free work from the free and open-source software community, but the rights that community is supposed to get under the AGPL v3.0 license? Those rights are ignored, as per their own convenience.
But don't worry, they do mention the "open-source" nature of their project with a hint at the license at the end:
> ONLYOFFICE is distributed under the AGPL v3.0 license, ensuring transparency and commitment to the open-source community.
What a joke!

Just a note: I have no problem with a software developer deciding under what conditions to distribute their software to users. If users become aware of the software project, it is up to them to decide whether or not they agree to those conditions. Because of the benefits that free and open-source software offers users and developers, I believe strongly in free and open-source software. Here, however, "free" does not mean "free of charge", but rather "free" as in "freedom". While I won't applaud someone who doesn't redistribute their software as "free and open-source software", I also don't hold a grudge against them.
However, I have a problem with the fact that, on the one hand, software is marketed as "free and open-source" software (apparently because it sounds good) while, on the other hand, the rights of the "free and open-source" software community are disregarded, abused, and trampled upon in such a despicable manner!
