I’m sure something can be done to prevent outbound signals from the device.
Yes, something could be done… by the exact company who has a direct incentive to serve ads in the first place. Are you going to install a 2nd chip made to block outgoing signals in the 1st chip?
It will never ever be solved by trusting the company who designs it to do the right thing.
That’s not the argument, you are saying it’s impossible to build a device that has input but no output to the same system. I’m saying you are wrong.
Sure, I’m wrong about something that wasn’t even the argument and I already clarified is possible, technically, but completely impractical for the application and does not exist.
By all means, send me the part number of a read-only connector. That would probably be very useful ti my work.
