In general, it is questionable whether you can even effectively protect your data today. It is officially known in things like Alexa that conversations are being made to improve the product, that Facebook collects a lot of data, that apptrends come from Russian developers who also store all the data or companies like Huawei in western markets lose their connection with new products because by espionage allegations the products of Google and co. No longer allowed to be used. Personally, I do not believe that somehow you can protect your data completely to a reasonable degree. Everyone has to know for themselves whether he likes it well, wants to fight it or sees the benefits that already exist and especially those that will come. Everything is networked and we give everything as end users. We all read no more terms and conditions, more or less use up to 5 different social networks or apps like Spotify, which we can now check by GPS our location, we no longer question. Are companies really interested in more than our data, such as the lifetime of a particular app, where we live or which shoe brand we particularly like to buy? Does that restrict us? Ever since whistleblowers like Snowden, we know that if you want it, you'll find that you can find out everything about us. So in this context, one has to ask oneself the question of whether one can remain true to an emotional principle or differentiate between instances for which we have always been glassed and become glass, or companies that improve their products. Of course it may be that these also resell data to the state. Is that in question? Clear. Can you prevent it? Yes, if you do not use anything anymore. Is that still possible today? I would say no. Do you make yourself glass? Yes. But as you have to ask yourself the question of how to try with a cardboard wall to protect a 12 meter glass front just because otherwise where go, if everyone does not care. I think the topic is often dominated by emotions and not by a rational questioning.
Is nice and good…
But what exactly is your question now?
The most effective defense is simply not to go along with the nonsense.
No reasonable person needs "social networks" or "Watsäpp".
Well
