someone on here a few months back recommended a free language learning org. they refused all corporate sponsorship and was dedicated to free accessible language learning, and seemed to teach differently than other methods i'd used. i went through a bunch of their arabic lessons on youtube (but I remember you could download the lessons too). and i can't remember the name of the org. searching isn't helping. i lost my bookmarks in The Great Phone Crash of 2018.
The networks that you connect to can spy on you---your cellular network, bluetooth, wifi, etc. To help mitigate these threats, you can disable those communications until you are in a safe place that you don't mind others knowing about. This can really only be guaranteed with a hardware switch---iOS now lies to its users when they ask to disable those communications, for example.
The software running on your device spys on you: the operating system itself often spies; the apps you install often spy. This is the fault of the individual _authors_---_they_ are the problem. Consider using free/libre software that empowers you and serves _you_ rather than its creators; it's much harder to hide secrets in free software. On Android, consider using only free software available in F-Droid. We also need fully free mobile operating systems, like Replicant and hopefully Purism's Librem 5 that is still under development.
Call out those that do harm---don't veil and protect them using statements like "your phone tracks you". Talks about the specific issues. Demand change and have the courage to reject them entirely. That involves inconvenience and sacrifice, but if we're strong now, then in the near future, perhaps we won't have to make any sacrifices, much like the fully free GNU/Linux system desktops we have today.
Translation: "Everyone else does it too, so it's okay."
And trying to lead the user to believe that they really do need all of this stuff. Do they "need" it to provide those services? Perhaps. Do they "need" to provide these services to millions of people that don't want, have never asked for, or are completely unaware of them? I think not.
