Re: Backdoor in KiwiSDR

Rob Robinett

I share Glenn and Stu's perspective on this issue.
Over the years John has demonstrated that he deserves our trust and appreciation for all of his work.
Hopefully all of this negative publicity doesn't drive him away from further work on the Kiwi.

I too trust John and have made an SDR available to him via SSH many
times without a moments hesitation. One thing a generation focussed on
"correct" pronouns forgets is the morals and ethics of the older
generation bare little resemblance to (many) of those today. People who
lived most of their lives before the internet would generally not have
stolen music or avoided paying for goods (like software).

I had a Chinese NVR that I had somehow forgotten the password to,
support did not have a way for me to personally reset it at the hardware
but if I just gave it internet access they would do it for me in
minute... yeah no thanks. Half the complication of my home network
subnets, NAT and firewall is aimed at using off the shelf CCTV bits
without inviting a complete take over of my home network or being base
for further attacks. It is probably illegal to export an item from
country X without enabling a gov backdoor.

The fact that so many KiwiSDR's are still online makes me think that
most users understand this event and have decided the intention was good
if the inclusion does not suit today's world.

Has made me view the reporting of these events slightly differently,
drama sells, click bait etc.
