How did posting online change from, "Be careful what you put online!" to many sharing a lot under real names?

I think it all started with Zuck wanting to turn Facebook profiles into the “Internet’s Driving License” or some shit about ten years ago: technologyreview.com/…/facebook-wants-to-supply-y…
Facebook Wants to Supply Your Internet Driver’s License

And new security measures protect everyone’s data.

Can confirm. Before FB, almost nobody told their real name online. Nowadays you can easily find out who is a racist and who believes in conspiracy theories just by looking at what they post. Usually there’s also their real name and face attached to the post so that you can be sure who you are talking about.

How did this happen? FB made it normal and almost obligatory.

Why did it happen? So that FB could make more money. Simple monkey brain people like to socialize and share stuff with everyone, and FB is simply exploiting that vulnerability.

I mostly avoided it so my memory may be off here, but weren’t there still a fair number of folks that posted to MySpace using parts of their real name and, imo slightly worse, using photos of themselves as profile pics? Real names are one thing but photos of yourself are just a dead giveaway.
Neither is very useful until you can correlate it with something else. Like, it takes a lot more effort to find someone in meatspace than in a database. Though, the number of databases with your face in them is a number that goes up faster every year.
That’s true, although as I recall there was often enough additional info even back then that someone determined enough could become a concern.
You aren’t wrong. There were also plenty of software-related mailing lists back in the day where folks used their real names regularly. And even if someone did go by a handle, their real name was often known anyway.
Yeah. and there were a lot of tech type folk that had a blog on domains that required ‘real names’ and more, that was quite often public.
