1/3 Thanks to Uwe Buermann I can now deploy @Fairphone, @LineageAndroid, @signalapp and other #FLOSS/#OpenSource tools in my family.
2/3 Backed with some technology related principles from R.Steiner he explained to pupils, parents and teachers of Waldorf school in Bratislava, how modern communication devices work, and voila.
3/3 Reg. principles: Roughly along lines of "don't use tram if you don't know how it works" Uwe explained basic workings of phones and Internet, then also highlighted some strengths and weaknesses.
Roughly in line with common #FLOSS motivations. Interesting, how stuff intertwines
