Lack of Transparency: No specific details on what or when they transmit.
Lack of Communication: Didn't tell customers they were putting this in place.
Forcing customers to employ additional network security on a network device if they don't trust what you're doing ... which is hard to do given the lack of transparency and communication.
>there must be some grievous harm telemetry causes that I am not aware of.
What you're not aware of is the same thing the rest of us aren't aware of ... and that is what is actually sent and what triggers that etc.
I respectfully disagree. It is also the fact that there's telemetry. It is not OK for me to punch you in the face just because I tell you I'm going to do it first. You shouldn't have to mitigate that risk. The risk wouldn't exist if I weren't punching you in the face.
That is telemetry.
In this case, Ubiquiti’s actions are particularly irksome because they’re changing a product after its sale to do something that would have caused many customers to avoid purchasing it in the first place if it had shipped that way — and without giving customers an easy way to turn it off.
