I think there's a bit more than that.
In their #information channel, last updated on July 12th 2024 @ 11:45 AM ET, the staff writes the following:
[Image ID: A screenshot from the official Octogon's Discord server, specifically on their information channel, of a message titled "Important Note From The Octogon Staff: Our policy on endogenic systems". Highlighted text reads: " [...] our stances on endogenic systems is known: Octogon's bot, app and communities are not intended to be used by those who identify as non-traumagenic systems of any capacity. [...] positive discussions of concepts such as purposefully creating alters, appropriated tulpamancy and system hopping are banned. ". ]
They add in that same message though, that they do not encourage syscourse in their server. I think that's because they don't have alot of moderation yet and they do not want to fall into controversy since they are clearly not prepared for the consequences and the harassment it may lead.
[Image ID: An extended screenshot of the previous one, text highlighted reads "Debate of these topics (commonly known as "syscourse" or "system discourse) is explicity banned. [...] Hate speech towards either side of the arguments is not tolerated". ]
Hence the infamous message in the #announcement channel from the server owner (made July 17th, 2024) that sparked another discussion in anti-endo spaces, where they say:
[Image ID: Part of a screenshot of a Discord message made by the server's owner, where it says: "We have a neutral stance on systems not caused by trauma. Our platform isn't designed for them nor around them. If you came here with the intention of sparking discourse regarding this subject, please leave. ". ]
There's also this screenshot from a message made yesterday by a mod that also supports this theory:

TL;DR I don't think they are truly endo-neutral, they are just trying to not express themselves because they know that it could lead their server into controversy if they take a solid stance on some syscourse subjects. The app, bot and community is still centered on DID/OSDD systems and is not made for people who identify under the non-traumagenic umbrella.
