alt Hacker NewsIt was always an option to have the technology without the bullshit. We can have GPS without allowing Google or Apple to track our every movement. We can have useful websites without allowing the people running those websites to mine every scrap of data we upload and sell our private information to anyone willing to pay for it.
It's not a requirement or law of nature that every technology sold must be used against the customer, we just haven't reached a point where we say enough is enough and outlaw such consumer hostile practices. Instead we've been allowing the corporations who seek to screw us over at every opportunity to gain more and more influence over the governments that could constrain them making it harder for us to fight back against the abuses we're subjected to.
Everything you just said is readily available now. You can use a FOSS OS on a mobile device with an offline mapping program. They were available before Google Maps was even a thing on Android 1.x. I know because I used to download them and use them without even having mobile internet in rural areas. The only thing stopping you is yourself.
