I think the average person just simply doesn't care about their privacy.
In some of the music communities I'm in the content creators are already telling their userbase to go follow them on threads. They're all talking about some kind of beef between Elon and Mark and the possibility of a boxing match... Mark was right to call the people he's leaching off of fucking idiots.
I think a big part is people don't understand the impact of what they are losing. It's not something tangible like their wallet or car being stolen, it's just "information" and they don't understand how that data can be used against them. Even when examples are given, such as the Cambridge Analytica incident, they think they are smart enough to be impervious to the manipulation so it doesn't matter.
Also anyone younger than probably 20ish has never known anonymity on the internet and so it’s hard to convince them to make sacrifices to convenience for something they’ve never had (and never will, no matter how much you try)
I feel like Cambridge Analytics stuff was about picking out who might be vulnerable to those types of political campaigns and by nature there's probably a bit of a correlation between that type of vulnerability and a lack of understanding of why their privacy is important.
The people who recognise it's important are unlikely to be the ones picked out by these groups anyway
