Just a Venn diagram. Anxiety / Linux users. You have some overlap but a large part doesnt. But the Linux users you don't hear about are the ones that obviously don't make you aware they run Linux, so they don't fit your bias here.

I have zero Social Anxiety. My work role is often doing corporate presentations or staff training etc.

But I have been a privacy advocate for the obvious reasons of government (or private citizen or corporate) misuse since two incidents: Canadian Government was caught spying on private citizens decades back, and a firefighter around the same time said for fun they'd drive around with their thermal imaging camera and watch people in their homes. Those two things made me realize I'd been taking the facade of assumed privacy for granted, and instead have to actively be private.

People should take privacy seriously but they don't, and it will become the downfall of freedom. It's already eroded in the UK and US where you can post a political meme and get arrested, or a warning to stop because the people in charge will cause you trouble otherwise.
