I never learned how that happened. We suspected that someone might have sneakily applied them during production or before delivery, as the trains were brand-new.
I doubt they were “official” stickers 😉
When the Munich public transport introduced new trains around 20 years ago some of them had porn images stuck to the inside of legs of some of the benches. You can be sure that teenage boys find them.
The numbers quickly dwindled but it took the company years until they had them all removed.
Ain’t that the truth. But I love the workflow they offer. You don’t have to go looking for new windows. You can easily pin applications to virtual desktops and I prefer the multihead model they use over the one used by gnome or KDE.
I don’t know what gave you the idea that a particular distro would be an especially good/bad choice for privacy, etc. They’re all GNU/Linux with only minor differences in compile-time options in the kernel and different defaults in user-space. But they’re just that, defaults. You can reconfigure them to your preference.
With that out of the way, the issue NixOS attempts to address is reproducibility. You get a central configuration infrastructure that defines everything, from partition layout, through user creation and package installation to software configuration. The central idea being that migrating to a new machine or setting up a new development environment should only take a few commands.
What you do with that is up to you. You can barricade the whole system if you like. The defaults are sane, but not overly focused on privacy, etc.
Also it’s quite a learning curve as the documentation/wiki is incomplete and/or outdated.
With the Fairphone you get more than just a replaceable battery. You get replaceable nearly everything. Also they do their best to ethically source the materials. In terms of ROMs there is also Iodé, also based on LOS, and if you go with a FP4 instead Ubuntu Touch.
