So if I put up a website at doxsyoc.com with your email address, phone numbers, home address, credit card details, social security number, daily schedule, bank statements and employment information you would presumably not try to have it removed because "Trying to suppress knowledge is never the answer".
I think you chose a weak interpretation of what they said to make your point. I don’t think that’s what they meant.
We’re talking about a tool here that attempts to aggregate all of a particular person’s social medial accounts. Social media is public. Everyone knows this, your are saying things and posting things with the expectation that everyone will be able to see them.
What you said is something totally different. Doxing someone’s private information is heinous. Nobody is arguing that is okay. I think the parent comment made a good point.
If tech can allow a tool like this to be possible, I think it is arguably better that everyone have access to it, instead of just bad actors keeping it to themselves.
