it's getting so hard nowadays

It's definitely not easy, but sometimes we just do the best we can, even if it's not the most that could be done.

Everyone has their own unique threat model. A random everyday person will have less need for personal privacy than, say, a government employee that works for an intelligence agency. Do what you can to protect what matters most to you, but don't stress if you can't upend your entire life to improve your privacy.

there are so many more important problems

You can support multiple solutions to world issues at the same time, without needing to make any individual one the most important one, or completely throwing out your other beliefs.

Privacy protects you from anything ranging from annoying ads, to targeted election misinformation, is key to dismantling the surveillance state that is regularly used to silence opposition to current political powers, and protects your right to free speech in a world where every government wishes they could control you just a bit more.

Privacy protects you from self-censorship. It keeps you safe from people who might want to harm you or your family for your views. It lets you protest oppressive policy.

Companies make money off your data. And what are these companies contributing to? Global warming through ever-expanding datacenters running AI models you didn't ask for. Political campaigns that endorse monopolies. The exploitation of third-world countries.

By taking away their ability to sell you for profit, you indirectly reduce numerous other harms.

I just can't remember why I thought it was something worth fighting for

The world is crazy. It's not weird to let things like privacy fall to the wayside when seemingly larger problems pop up, but privacy doesn't exist in a vacuum. Everything is interconnected, and privacy directly impacts these other issues.

It's okay to just do what you can. the world isn't perfect, and neither are we.

Privacy directly helps dismantle systems of power, surveillance, advertising, and manipulation. So if that's worth it to you, then keep fighting.
