Passenger information systems in public transport. Some might run some kind of embedded windows, but most run on Linux. Certainly here in Czechia, but I believe it’s common at east throughout the Central Europe.

I would leave out the Serbs, you might get answers you won’t like.

It has an option to use Open RC init system instead of systemd. Systemd probably isn’t as annoying anymore but I can’t be arsed to make the switch.

Czechia has a racism problem sure, but that map has no data on actual Eastern European countries so there is no comparison possible. Also you can’t reduce the question of being Eastern European on one metric. Was Belgium under Leopold II. Eastern European? Nazi Germany? USA before 1863?

Please do not refer to Czechia as Eastern Europe. It’ simply wrong: Czechia rejected the Eastern Christianity even before the Great Schism, it never was a part of the Russian Empire and it spent most of the last millennium as a part of the HRE. The only connection - being part of the former Eastern block was so long ago that in only 4 years Czechia will be a EU member longer than it was occupied by the USSR.
