That is not true unfortunately. I tend to be very left wing socially - economically I'm more left of center - and that was reflected on my social media as well - either pushing me towards more radical content or stoking anger with more radical right wing content to get me riled up and coming back for more.
I ended up with a growing hatred and emnity for a growing number of people and "groups", and black and white thinking. Even though I was aware that I was being manipulated, it was still impossible to sit on a high horse above the fray.
It's quite easy to manipulate human minds, even ones that are careful and aware. We can all be manipulated. It's why advertising works, for example.
The only thing to do really is to not play that game. Avoid advertising, avoid other content curators deciding what you get to see and telling you how to reason, etc... realise that most people are empathetic, that most people want what's best, and those that are radical have been manipulated to be that way, sadly.
Several points:
Lots of information is public, such as your address. That doesn't mean somebody explicitly publishing your address for the purpose of harassing you isn't committing an offence.
Some celebrities can't fly on passenger planes for their own safety and even that of others or the proper functioning of infrastructure. Can you imagine Taylor Swift trying to fly on a public carrier? She would get mobbed at the very least. At worst she might be putting her health or even her life in danger. Especially now that the MAGA morons are attacking her.
I find Taylor Swift bland as beige, I don't get the appeal at all, and I think Musk is a rabid twatwaffle. I also don't believe anyone should really get to be so wealthy. Still, there are good reasons why one might need to travel by private means without their movements being broadcast.
