I still like them. I have almost no real complaints about their products. They just work for me. Here is an example: I had a Netgate with pfsense for my home gateway. My primary home internet provider can be a little flaky, so I have a beefy 5G gateway backup. It was way too hard to configure one of the ports to support automatic WAN failover. The, less expensive, unifi product just worked. It was just a simple setting in the gateway's management UI. The information provided in the dashboard is rich and it implements things like constant QoS monitoring that has a nice plot. It adopts and manages my home wifi and makes it super easy to configure channels, analyze congestion, and do all the deeper technical configuration I could ask for.

Another example, I had Frigate set up on a home rolled NAS. Again, it worked alright, but it always stole time from me. It always needed a little maintenance or tweaking or thinking. I bought a UNVR and modern Unifi cameras. Adopted, zero thinking or management from me. I still retain control of my data and it respects my privacy. It isn't perfect, but at the price point it solved meaningful problems I cared about in both cases. Yes they are commercial products and not open source, but they are priced reasonably to my eyes (the UCG ultra was actually cheaper than the netgate). That makes me a happy customer.

I have run their wifi APs for over a decade with no problems. It's not perfect, I know there are still privacy concerns. No company is really perfect, but they are good to me.
