I closed my Facebook and Instagram accounts over a year ago and have not missed it for a single day. I am still dreaming of leaving WhatsApp as well, but that proves to be more difficult.
Since then, not a single month have gone by without news coming out about Facebook’s blatant disrespect of its users, privacy and ethics.
I have made my choice, and I encourage you to make yours. If you disagree with Facebook and its policies, leave. You might be one account, but if you are one among millions, you will make a difference.
