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.
To be fair, you basically have to give up on your privacy if you want to be a public figure these days. To make it most musicians have to constantly evangelize themselves, which means being omnipresent on social media platforms.
Posting your band's tour dates on Facebook doesn't really even change your privacy status that much.
Whether you have a Facebook account or not, Facebook tracks you around the web. Data brokers sell your data. Your cell phone company sells your location and browsing history, etc.
People over-estimate how much not using any given social media app really matters.
Now granted, installing it on your phone gives them a level of data they wouldn't have from a web browser. That's probably why Threads is phone-only.
Fair enough. I took efforts a few years back to eliminate all my social media, and started a new reddit (now lemmy) account and made efforts to be more anonymous
I'm sure they collect some info on me, but for me its about not just handing it over.
