I'm a bit out of the loop on Ubiquiti, but IIRC they pushed out an update where telemetry was not optional, and then after the backlash they may have pushed out another one with slightly more configurability.
If you buy professional gear from an organisation that would think that was acceptable in the first place, you might want to re-evaluate your preferred suppliers anyway.
Sadly, even Ubiquiti gear has recently been criticised for doing the built-in phone home thing.
