Nothing wrong with the Czech Republic per se, but it’s at the far outskirts of the “Western world” and is nowhere near any modern tech hub. Hot tech companies tend to be run from California, Seattle, New York, London, etc., or alternatively Shanghai, Beijing, Tokyo, etc., not from small states in Central Europe far from either pole. Thus the company being run from Czechia is a sign of how far it’s fallen.
This isn’t a “jab” at the Czech Republic at all, which is by any measure a wealthy, developed, and well-run country where people have a high quality of life.
