Privacy
I rant about privacy quite a lot, a brief summary of my stance:
Privacy is a fundamental human right, it's about choosing what to share, who to share it with and when to share it. We all do this on a daily basis, it's a basic social function. There's nothing wrong with closing a bathroom door when going to the toilet, or not wanting your employer listening your rant to your friends about your bad day. It's not nefarious or sinister.
What's acceptable today might change tomorrow, what you think years ago may seem stupid and harmful to you today. When these choices weren't indelibly recorded on the internet forever, it wasn't as much of an issue, but people are more forgiving than you think and have short memories. Today these bad decisions can now stick with you forever, being used by banks, employers and even governments on making decisions about your life. Whilst you might not think any of this is bad now, can you be sure this won't be misunderstood, taken out of context, or simply judged differently by future standards?
If you look toward the people who are so keen for you to give up your privacy you'll notice most of them fight for their own privacy very hard. How much information does Google, Meta, etc give you about how they work and operate? Are your politicians open books with no skeletons in their closet or hidden interests? Privacy isn't about having something to hide, nor having to justify every thought, mistake and bad day to people who may not extend you the same courtesy, it's about choice.
