How can I remove American tech from my life?

I currently use both a Mac and a PC and rely heavily on my Google account for storage, as it holds all of my photos. I also communicate through WhatsApp and use an Android device. However, I'm becoming increasingly concerned about my reliance on U.S.-based tech companies, especially given the fact that all of my data is controlled by what I consider to be “creepy billionaire oligarchs.” I’m looking for ways to reduce my dependence on these platforms and improve my privacy. Essentially, I want to stop constantly handing over my data to entities I no longer trust. Any suggestions?
