Czech Mate for GNU/Linux on the Way
Czechoslovakia became two countries in the early 90s. The Slovak Federative Republic adopted Windows in the mid 90s (like most countries), but that has changed in recent years as Windows lost its footing since past years and GNU/Linux approaches 5%:

The Czechs have similarly moved to GNU/Linux (5% exceeded earlier this month, now a bit less).

Czechoslovakia is having none of that "peace for our time" with Microsoft. █
