It may be auto-updating by default, but that can be trivially disabled. Likewise, their cloud connectivity/management is optional. I'm running without issue multiple air-gapped Ubnt networks using their self-hosted controller software.

If it's airgapped, what do you care about it being backdoored?

Airgapped doesn't necessarily mean it can't be accessed remotely...

Yeh but it is still closed source, no? I guess if it is air gapped that could be fine, but we are talking mid level network gear here, so for 99% of its use, it isn't air gapped. It is enabling broader connectivity. So you would have to trust the closed source software at some point.
