I saw your exact question elsewhere, so I'll reply with my exact same answer:
I personally grew a strong distaste for several reasons. When I first started my homelab I was ready to go all in with Ubiquiti. Equipment looked nice, great looking UIs, great price. Seemed like everything was perfect for the prosumer. I bought some access points and a UDM pro to start, with plans for some POE switches next. First thing that irked me was that I had to log into everything through the cloud. And it wasn't possible to set up the UDM and access points at the time without a cloud account, though I know this has since changed. Second was that they were sending all kinds of telemetry to HQ. One of the reasons I set up a homelab is for privacy and data sovereignty, so having my low level network equipment spy on me is a huge no-go. The third thing that really pissed me off is that there was no way to manage any clients on my network that didn't go through a Ubiquiti access point. I had an old Airport Pro that I was using and all the clients that connected through it were not visible to the UDM pro. Both official support and the reddit forums said it wasn't possible and it didn't make sense anyway, and gaslit me and even removed some of my posts and comments. What is the point of a firewall if you can't disable traffic to some clients (e.g. I didn't want my robot vacuum phoning home to china). I SSH'd into the UDM and indeed see the vacuum in the ARP table so there was no technical reason to not allow me to set firewall rules for it in the UI. I mean the UDM gave these clients DHCP addresses, so it's obvious that the UDM was aware of them. It became clear - it's a business lock-in strategy to force you to go all-in on Ubiquiti equipment. They don't support heterogeneous mixed-vendor networks. I said fuck that and returned it all. Switched to open source products like OPNSense and used professional equipment from EBay and couldn't be happier. Way more control for the same price, no spying, and no vendor lock-in.
