Have you heard of the Digital Independence Day? It is on the first sunday every month. You are encouraged to make a switch from at least one big tech service to an alternative on that day - in the name of freedom and democracy.
The Digital Independence Day was announced on the Chaos Communication Congress in germany at the end of December. More information about it (in German): https://di.day
