I use an RSS reader to curate my Lemmy feed, which means I see every post, including deleted ones. Every so often, posts will crop up with pessimistic content such as "Why try anymore?" etc. Most of the time these are a result of privacy burnout, where the individual has a threat model that is too strict for their own tolerance.
We all wish we have perfect privacy. We all wish the world could be more pro-privacy than anti-privacy. One day, that may be the case. For now, we have to accept that nobody can be completely private. Privacy is a spectrum, and doing what you can to minimize data collection goes a long way. You can't become private overnight, so taking small steps like these means you can grow a strong foundation for future privacy. Privacy takes time, so take it as slow as you need to.
Even if a company already has your data or another means to track you, by minimizing you are making it harder for them to extract that data, and it increases the odds that your data becomes stale. By caring about privacy to begin with, you're showing companies and other people that the data collection is not ok.
I've been a privacy activist for years now, and I will also face periods of privacy burnout. I handle it by stopping, taking a step back, and reevaluating my threat model. It's good to take breaks like those, because it means you don't push yourself past your limits and become burnt out.
It's really easy to get caught up in the "breaking news" of privacy, too. This is more of a personal stance, but getting caught up in politics and news often leads to stress and makes it harder to make real progress. (This is one of the reasons I use an RSS reader, I can curate my information without stressful headlines.) You don't need to use the most private software or jump ship the moment anything goes wrong. If you feel you need to switch, do it when you have time and when it won't cause problems elsewhere.
Take a look at how far you've come, and realize that even if you're not where you want to be yet, you've taken steps to get there. Every person who starts to care about privacy, even you, is one more person to help make the world a more privacy respecting place. It may not seem like you make that much of a difference, but it's not just you. You and everybody else who cares about privacy makes a huge difference.
Don't give up now. Privacy is an uphill battle by design, but the payoff is worth it.
Good luck!
