Google doesn't have a privacy problem. Google IS the problem.
Are you a happy Google user? Think about it: By default, Google has access to:
- Your web activity
- Your location and address
- Your emails
- Everything you type on your phone's keyboard
- Your Wi-Fi credentials
- Your age and gender
- Your WhatsApp history
- Your photos and voice samples
- Your payment history
- Your passwords
The list goes on: just go to Google Takeaway and download the archive. Enjoy.
"But they're just using it to show me their ads!"
Maybe, but according to the Patriot Act, the US government and intelligence agencies have automatic access to your data. This process is fully automated and your data is scanned on a daily basis.
Don't think you're too small and obedient and nobody cares about you. This data can be used to influence your political views or against your friends, colleagues or employer.
Next problem: You cannot just move your data to another provider. There are no open standards for network cloud services. Moving your data is difficult and painful. You are locked in.
You can choose from many European services, but remember: the political landscape can change. Do you have a guarantee that Switzerland, Germany, or France won't become the next U.S., Russia, or China?
How will you move your data from Proton or Tuta? What can stop developers from building backdoors into their services? Basically, only their promises. Not much.
You should be able to switch providers if you care about your privacy.
So far I have only found one portable solution: Nextcloud. It's an open source workspace of German origin used by several European providers (e.g. murena.io from e.foundation). You can switch between providers or even host it yourself.
Moving your data is not enough. You shouldn't use plain android or ios if you don't want your phone to deliver your secrets to Donald's minions. But it can be a good first step.
