The guy’s logic is “if only we had allowed a small backdoor from the start they wouldn’t be forced to install a large backdoor now”. Other technologies that were open to the law were endlessly abused for surveillance.
His theory is bunk, there is absolutely no middle ground to be had with the people who want a backdoor. There are no small backdoors.
What do you consider a backdoor though? Saying that devices must have parental controls isn't a backdoor. Saying that devices must scan your ID is a backdoor to break anonymity, but is he saying that?
If we had parental controls that actually worked it would forestall any talk about ID scanning because parents could just enable parental controls.
