That is true, for real life it's harder but as for digital, again. Until I'm here I think my data are protected simply because I'm pretty often around my devices and when that won't be the case I would want it to stay that way.
To answer to your second reply, I do understand that evryone has their own secrets. I know that and I'm pretty sure that whatever secrets the people I know may have won't bother me. We all have our things that might appear weird, strange or wrong to others and that's common to everyone. But to me, if I applied that tought there would be no point in being into this foss and privacy movement at all. If I don't care about my friends knowing my secrets then why would I care that a computer does? I've spent the last copule years trying to find alternatives to companies like google and I tried finding trusted software while also minimizing the amount of data I have online (I have around 30 accounts compared to the 100+ I had when I started) so since I'm so invested in this I aim to improve as much as I can.
100% privacy won't be possble until the day I dig a hole on the bottom of the ocean to live in but for whatever can be done I aim to do it.
I'd sum up all this into something like I'm more of an "everything or nothing" kind of person when it comes to digital stuff, since I put effort into not using the convenient mainstream options, might as well always take it to an upper level.
