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.
