Personally, I have no problem not being
anonymous online. But I do prefer to have
privacy online.
Some folks conflate them, but while they are related, they are not the same thing.
Sites like HN provide privacy through pseudonymity (which is, essentially, the "solution" prescribed by the author of the blog post), allowing those I interact with here to know that "I" am "Nobody9999".
Unsurprisingly, that's not the name on my passport. But on HN, you can be relatively sure (assuming I'm not also operating sock-puppet accounts as well) that my thoughts, ideas and expression are from the same person.
I preserve my privacy by not using my "legal" name here. The combination allows me to freely express myself without being tracked down, doxxed or otherwise abused by those who might disagree with me.
As for other places on the internet, I generally don't utilize sites that require verification of my personal details (an excellent example is ChatGPT, which requires not only an account, phone number verification as well), not because I'm engaged in evil/illegal/nasty behaviors, but because my business is my business and no one else's.
That's at least an attempt at preserving some semblance of privacy, but doesn't really provide anonymity.
While (as others have mentioned), my electricity provider, my landlord, my ISP, my mobile device service provider and my doctor all know who I am, where I live and an astonishing amount of information about my life, for the most part that's necessary to participating economically in society.
As such, especially given the lengths to which ISPs and mobile service providers go to to collect information about my activities, my privacy is significantly curtailed. That generally pisses me off, not because I really have anything to hide, but because (and I'll say it again), my business is my business and no one else's.
while I do understand the blog author's point of view, rather than creating an alternative persona online, I'm just me and mostly share my thoughts pseudonymously without trying to create an alternative backstory for those pseudonymous identities.
However, those who choose to use online resources that require verification of their identity, may need to take additional steps to preserve their privacy/pseudonymity. I choose not to engage in those forums and, as such, my privacy is improved a little.
Is that sufficient for me? No. Unfortunately, there's a limit to what I can do while still living "on the grid." And since I have no interest in squatting in a lean-to deep in the woods, I do have to give up some privacy.
I'd love to live in a world where collection of PII was the exception rather than the rule, but those my countrymen (with a very few exceptions) elect to legislate and execute such laws as are legislated don't seem to give a rat's ass about privacy, unless theirs is impacted.
And more's the pity.
Edit: Fixed typo.
