I found a very suspicious-looking wiki here: https://www.cablefree.net/support/radio ... Manual:TOC which looks like a carbon copy of RouterOS' wiki. It seems like "Mikrotik" has been replaced by "CableFree" and "RouterOS" is now "RadioOS." Also, both Mikrotik and CableFree claim to have been founded in 1996. What gives?

There is licensing - and branding packages available to routeros users.

Depending how much you want to spend - im sure there's no limit to the amount of customisation you can ask for. It is more likely this is branded RouterOS as a commercial customer - and they are using integrated boards in their wireless systems rather than something nefarious.

CableFree is a distributor. They have used a branding package, like the above poster explains.
