This thread is tending towards flamewar so I'll try to dial back, but I do want to respond.
> You are being manipulative an trying to make it look that people who disagree with you are somehow pro-child abuse.
I am not doing that. You described my position as an "alien morality", to which another poster seemed to agree. I was responding to that by clarifying the actual moral point I was making. For the avoidance of doubt, I am not arguing that you are pro-child abuse.
> In saying "Does the tech industry have any alternate solutions that could functionally mitigate this abuse?" you are trying to pain a picture in which child abuse is somehow "tech industry" fault.
Yes, this is basically a correct understanding of my position. I am stating that the problem has been massively exacerbated by the adoption of E2EE by the tech industry, and that the tech industry therefore has a moral responsibility to deal with the unintended consequences of its own action.
> the truth is that personal communication was private for hundreds of years, because it was impossible for the state to listen in on everything.
The truth is that in pre-internet times, networks of pedophiles could be dismantled by the state, partly through surveillance -- see https://en.wikipedia.org/wiki/Paedophile_Information_Exchang... for a supporting example.
