I leave the GAFA two month ago, i don't have a account of Google, Amazon, Facebook or Apple. For sure I keep my phone i use android for sure but it working, i just can't use play store but i find a alternative. I download my apps with extansion apk on duckduckgo. If some people thinking to leave your account from GAFA you can, i'm living proof. And a alternative to use always google for go to on your favorite website, you can just write the url in the bar or just be mark in your favorite. It sure is difficult to not use google search but if you can less often, i think is the good way. After that a alternative for amazon is ebay or alibaba and some other company, but i recommend to buy local, it depend of your citizen involvement. Ah! And for facebook my friendship is better now because i take more time of quality with them. And i try always to have a good relationship with the new people i met, i try to be more human and i think that make the difference. Finally i construct my own mailbox with a help of OBNL. I feel more free and ethic but the important it to follow your value
