Personally I hate the way they're going towards cloud accounts and dedicated management boxes. We used to be able to just install a docker to manage everything but the latest hardware ranges (eg their video offering) require dedicated management hardware. They're also pretty slow with uptake on new standards like WiFi 6 and now 6E.
The ideal selling point of ubiquiti was self-managed near-enterprise quality hardware with free self-hosted management and decent hardware prices.
I can't fully blame them because I know venture capital idealises subscription pricing and data mining right now but it won't work for me and it's annoying having to look for another option again when I'm invested in their ecosystem.
But anyway it would be interesting to read more about what's going on behind the scenes.
