I then wrote up a post about my motivation for leaving which I shared on my Facebook: https://nilsnh.no/2018/04/04/leaving-facebook/ I figured it would be better to be vocal about leaving instead of just disappearing without a word. I answered questions and helped some friends join me on Signal.
Personally, I'm happy to be investing more of my time in platforms which respect my privacy. And I eagerly encourage people I meet to consider ethically-minded platforms like Signal.
Ultimately, I hope to see real, legal consequences towards corporations that disrespect the privacy of its users. Also, if monopoly laws were revised for the digital age we might see that some large corporations should be broken up in order to cultivate better competition.
